The Perfect Storm: When Your Menopause Meets Her Puberty
An interview between femme and Grace Gordon, founder of FluxxBox Grace, you’ve coined the term “the perfect storm” when talking about menopause and puberty clashing in the same household. Can you explain what you mean by that? "Absolutely. The “perfect storm” is when a mother is going through perimenopause or menopause at the exact time her daughter is starting puberty. It’s this collision of two intense hormonal life stages, one where your oestrogen levels are dropping, and one where hers are skyrocketing. Imagine mood swings, irritability, anxiety, and sleeplessness… on both sides. It’s not just a challenge for our bodies, but for family relationships too." Why do you think this is becoming more common? "There are two main reasons. First, puberty is starting earlier than ever. Second, more women are having children later in life. If you had your daughter in your mid-to-late thirties, by the time she’s hitting puberty, you may be entering perimenopause. So while she’s finding her identity and pushing for independence, you’re trying to navigate the emotional and physical changes that menopause brings. It’s a hormonal overlap that’s not just inconvenient, it can feel overwhelming." What does that actually look like day-to-day? "On a daily basis, it can mean there’s a lot more tension in the house. She’s pulling away because that’s what teens do, she needs to develop her own identity, but at the same time she still needs you as her safe place. Meanwhile, your own hormonal shifts during menopause might make it harder to stay calm, patient, and resilient. You might find yourself snapping more easily, or feeling emotional for no obvious reason. Suddenly there’s a lot more shouting, door slamming, and sometimes even silent standoffs." That sounds exhausting. How do mothers begin to “weather the storm”? "The first step is awareness. Recognise what’s happening, both in your body and in hers. Notice your triggers and be honest about them. When you feel your stress levels rising, try to pause and take deep breaths. Remind yourself that you’re both riding an emotional rollercoaster." Should mothers talk openly to their daughters about menopause? "Yes, but with sensitivity. They may be open to talking about it or may not be in the headspace to hear about your experience at the moment. You could say something like, “I’m going through menopause right now, and my emotions can be a bit all over the place, kind of like what you’re feeling.” This normalises hormonal changes and helps her see that emotions are a natural part of our life cycles. It’s about creating space for mutual understanding." How important is shared activity in this? "Incredibly important. Shared activities create non-confrontational opportunities to connect, (where the focus isn't Puberty or menopause). Exercise together, cook together, or have those brilliant conversations in the car when you’re not making direct eye contact, those can be surprisingly honest moments." Let’s talk about self-care for mothers. Why is that so critical during menopause? Because you cannot pour from an empty cup. If you’re running on fumes, your patience, emotional regulation, and resilience will suffer. During menopause, prioritising good sleep, balanced nutrition, and stress management isn’t indulgence, it’s survival. And your daughter is watching. She learns emotional regulation by seeing you regulate your own. You’ve mentioned that menopause and puberty clashing doesn’t have to be purely negative. How so? Exactly. While being in the middle of The Perfect Storm can feel like chaos, it’s also an opportunity for deeper connection. You’re both going through hormonal transformations, just at opposite ends of the spectrum. You can empathise with her on a unique level, because you understand what it’s like to have your hormones driving your emotions. This can make you a more compassionate and insightful guide for her. Many parents worry about getting “the period talk” right. How can they take the pressure off? That’s why I created FluxxBox, the complete first-period confidence kit. It gives parents a practical, thoughtful way to prepare their daughters for their first period, without the stress of wondering if they’ve covered everything. Menopause can make you feel emotionally and mentally drained, so having a tool that’s ready-made for this milestone can be a lifesaver.

Menopause can make you feel emotionally and mentally drained, so having a helpful tool that’s ready-made for this milestone can be a lifesaver. What’s inside a FluxxBox? Everything a girl needs to feel confident and prepared, feel-good treats, age appropriate and holistic educational materials, and things to make her feel supported. It’s about giving her the knowledge and tools she needs, so her first period and her cycles are something she understands for life, not something she fears. You’ve spoken about conversation being the starting point for confidence. How does that tie in with your mission? Confidence starts with knowledge, and knowledge starts with conversation. Whether we’re talking about puberty or menopause, silence breeds anxiety. When we create open dialogue in our homes, we help our daughters see these changes as normal, healthy parts of life. For mums who think their daughter might be close to starting her period but aren’t sure, do you have any resources? Yes, we have a free quiz designed for parents to take alongside their daughters. It helps you spot the signs that puberty is progressing and estimate when her periods might begin. It only takes five minutes, but it can make a huge difference in feeling prepared. And during menopause, when your struggling with things like brain fog, a clear, structured tool can be incredibly reassuring. What’s your final piece of advice for mums in menopause navigating this “perfect storm”? Give yourself grace. You’re managing menopause and parenting a child through puberty, and that’s no small feat. Don’t try to be perfect. Focus on connection over perfection. Take breaks when you need them. And remember that both you and your daughter are learning how to navigate big life changes, side by side. Want more support for your daughter?

Using Cycle Tracking to Manage Conditions like PCOS and Endometriosis
For many people, reproductive health conditions like polycystic ovary syndrome (PCOS) and endometriosis don’t just affect fertility—they impact daily life. From unpredictable cycles to painful symptoms, these conditions can feel like they’re running the show. That’s why using cycle tracking to manage conditions like PCOS and endometriosis is such a powerful tool. It’s not just about fertility awareness. It’s about gaining knowledge, spotting patterns, and having real data you can use to take back some control. And with Tempdrop, the process becomes simpler, more accurate, and more reliable than traditional methods. Why using cycle tracking to manage conditions like PCOS and endometriosis matters Both PCOS and endometriosis can make cycles irregular, painful, or difficult to understand. Doctors often say “keep a cycle diary” — but when your periods don’t follow a predictable pattern, that advice can feel frustrating. By using cycle tracking to manage conditions like PCOS and endometriosis , you get more than just a diary. You get: Insight into whether ovulation is happening Data on how long your cycles really are Patterns between hormone shifts and symptom flare-ups A clearer way to advocate for yourself with healthcare providers This kind of information can make all the difference in day-to-day management and long-term treatment plans. How Tempdrop Makes Cycle Tracking Easier Traditional basal body temperature (BBT) tracking requires you to wake up at the same time every morning, take your temperature, and log it. For people with disrupted sleep or unpredictable schedules, this is nearly impossible. Tempdrop changes the game. You wear it on your arm overnight, and it automatically records your temperature while you sleep. The app filters out “noise” from restless nights and gives you a reliable chart of your cycle. For anyone using cycle tracking to manage conditions like PCOS and endometriosis , this means: Less stress and fewer missed readings Accurate confirmation of ovulation (when it happens) Data you can actually trust, even with irregular cycles Managing PCOS with Cycle Tracking Polycystic ovary syndrome is one of the most common causes of irregular ovulation. Some cycles may be anovulatory, while others are delayed or unpredictable. This can make it hard to know when (or if) you’re fertile and to understand how your body is working. By using cycle tracking to manage conditions like PCOS and endometriosis , you can: Confirm whether ovulation is occurring in a given cycle Track how long your luteal phase lasts when ovulation happens Identify trends that might otherwise be invisible (like recurring long cycles) With Tempdrop, you don’t have to guess whether a bleed is a true period or just breakthrough bleeding. Temperature data helps you see whether ovulation actually occurred. That clarity is invaluable for anyone navigating PCOS. Managing Endometriosis with Cycle Tracking Endometriosis isn’t just about painful periods—it often brings fatigue, digestive issues, and inflammation that can flare at different points in the cycle. Without tracking, it can feel random and overwhelming. By using cycle tracking to manage conditions like PCOS and endometriosis , you can start connecting symptoms with hormonal phases. For example: Pain flares may intensify during the luteal phase Fatigue may peak around ovulation Digestive changes may line up with menstrual bleeding Tempdrop helps confirm where you are in your cycle, so you can connect your lived experience with real hormonal shifts. That awareness makes it easier to prepare, adjust routines, and advocate for better support. Turn Data into Advocacy Healthcare appointments for PCOS or endometriosis are often short, and it can be hard to explain the complexity of your symptoms in a 10-minute slot. By using cycle tracking to manage conditions like PCOS and endometriosis , you bring evidence. With Tempdrop data, you can show your doctor: How often ovulation is (or isn’t) happening Cycle lengths across several months Symptom patterns tied to hormonal changes This makes conversations more productive and can speed up diagnosis, treatment, or referrals. Emotional Benefits of Tracking Living with PCOS or endometriosis can feel unpredictable and sometimes isolating. One of the overlooked benefits of using cycle tracking to manage conditions like PCOS and endometriosis is the emotional reassurance it provides. Instead of feeling like your body is working against you, you begin to see patterns and explanations. That knowledge doesn’t erase the challenges, but it can reduce anxiety and increase confidence. With Tempdrop, the process feels less like a chore and more like a supportive routine. Practical Tips for Getting Started If you’re considering using cycle tracking to manage conditions like PCOS and endometriosis, here are some tips: Be consistent – Wear your Tempdrop every night for the best results. Log symptoms – Use the app notes to connect physical changes with cycle phases. Be patient – Irregular cycles may take months to reveal useful patterns. Combine tools – Track cervical mucus, bleeding, and lifestyle factors alongside Tempdrop data. Share results – Bring your charts to appointments to strengthen conversations with healthcare professionals. The Bottom Line Conditions like PCOS and endometriosis can make cycles feel like a mystery. But by using cycle tracking to manage conditions like PCOS and endometriosis , you gain insight, clarity, and confidence. With Tempdrop, the process becomes easier and more reliable, even if your cycles are irregular or symptoms unpredictable. It’s not just about fertility—it’s about understanding your body, improving communication with doctors, and making empowered decisions about your health. Because when it comes to chronic conditions, knowledge really is power—and Tempdrop helps put that power back in your hands. Laura Cartwright Laura Cartwright is one of the founders of femme health.

Tracking Your Cycle During Perimenopause with Tempdrop
Perimenopause is often described as the “in-between” stage: not quite menopause, but not your usual monthly rhythm either. Hormones fluctuate, cycles become less predictable, and symptoms can feel confusing. For many women, this stage starts in their 40s, but it can arrive earlier. The challenge is that while your body is changing, it’s not always easy to make sense of what’s happening. This is where tracking your cycle during perimenopause becomes incredibly useful. Instead of relying on guesswork, you can gather real insights into how your body is shifting. And with the help of Tempdrop, you can make sense of irregular cycles, spot ovulation when it still happens, and feel more in control of this life transition. Why Tracking your Cycle During Perimenopause Matters Perimenopause isn’t a straight line. One month you might ovulate as usual, and the next your period may be late, early, or missing altogether. For some, hot flushes, mood changes, and sleep problems appear long before cycles stop completely. By tracking your cycle during perimenopause , you get answers to important questions like: Am I still ovulating? How long are my cycles now? Are my symptoms connected to hormone changes? Is there a pattern to the unpredictability? This isn’t just about fertility—it’s about knowledge. The better you understand your changing cycle, the easier it is to make informed choices about your health, wellbeing, and daily life. How Tempdrop Supports Tracking your Cycle During Perimenopause Traditional basal body temperature (BBT) tracking can be difficult at this stage of life. Waking up at the same time every day to take your temperature is tough enough without night sweats, disturbed sleep, or busy mornings. Tempdrop offers a more practical solution. You wear it on your arm overnight, and it automatically records your temperature while you sleep. The app smooths out any irregularities caused by restlessness or inconsistent sleep schedules, giving you reliable data without extra effort. For women who are tracking your cycle during perimenopause , Tempdrop can highlight: Whether ovulation is still occurring in some cycles How long the luteal phase lasts Shifts in cycle length over time Connections between symptoms and hormonal changes Spotting Ovulation When Cycles are Irregular One of the most confusing parts of perimenopause is not knowing if or when ovulation is happening. Some cycles are anovulatory (meaning no egg is released), while others are normal. By tracking your cycle during perimenopause with Tempdrop, you can see the subtle rise in temperature that signals ovulation. This gives you clarity—whether you’re curious about fertility, wondering if contraception is still necessary, or just wanting to understand what your hormones are doing. Even when ovulation becomes less frequent, knowing when it does occur helps you make sense of your symptoms and plan around your cycle more effectively. Connecting Symptoms to Hormone Changes Many perimenopausal symptoms—such as mood swings, anxiety, hot flushes, or fatigue—are linked to fluctuating hormones. But when those symptoms appear randomly, it can feel unsettling. By tracking your cycle during perimenopause , you can start to connect the dots. Maybe night sweats are worse in the luteal phase, or mood changes peak just before your period. Tempdrop provides objective data, so you’re not left wondering whether these experiences are random or hormone-driven. This knowledge can also be incredibly helpful if you decide to speak with a healthcare professional. Bringing cycle data and symptom patterns to an appointment makes it easier to have a productive conversation about treatment options, whether that’s HRT, lifestyle changes, or other support. Emotional Reassurance in a Time of Change Perimenopause can feel like losing control over your own body. Cycles that were once predictable may now come with uncertainty, and the physical changes can affect confidence and self-esteem. Tracking your cycle during perimenopause doesn’t fix everything, but it can help you feel grounded. Instead of being blindsided by irregular periods or unpredictable moods, you’ll have a clearer sense of what’s happening and why. For many women, that reassurance is powerful. It shifts the perspective from “my body is failing me” to “my body is changing, and I understand how.” Practical Tips for Tracking your Cycle During Perimenopause If you’re ready to start tracking your cycle during perimenopause with Tempdrop, here are a few simple tips: Be consistent – Wear your Tempdrop nightly for the most accurate picture. Log symptoms – Use the notes feature to connect temperature data with real-life experiences like sleep changes or mood shifts. Combine signs – Cervical mucus and cycle length still matter, even in perimenopause. Together with Tempdrop, they give a fuller picture. Be patient – Patterns may take time to emerge, especially if cycles are irregular. Share your data – If you talk to your GP or a menopause specialist, Tempdrop charts can make the conversation easier. The Bigger Picture While fertility may no longer be your focus, tracking your cycle during perimenopause is still an empowering practice. It helps you recognise the changes your body is going through, anticipate symptoms, and approach this transition with knowledge rather than uncertainty. Tempdrop makes this process simple, even when sleep and schedules aren’t. It’s less about perfect data and more about giving yourself insight, compassion, and confidence during a stage of life that can otherwise feel overwhelming. The Bottom Line Perimenopause is unpredictable, but it doesn’t have to leave you in the dark. By tracking your cycle during perimenopause with Tempdrop, you can understand what’s happening in your body, connect symptoms to hormonal shifts, and navigate this stage with more clarity. This isn’t about controlling perimenopause—it’s about making peace with it. And having tools that support you, rather than add stress, can make all the difference.

Using Tempdrop When You’re Trying to Conceive
When you’re trying to conceive , you expect it to take a few months. But when those months stretch into a year—or even longer—it can feel like a mix of frustration, self-doubt, and endless questions. In the UK, you usually need to wait two years before being referred for fertility investigations if you’re under 35. That’s a long time to feel in the dark about what’s happening in your body. This is where cycle tracking tools like Tempdrop come in. They don’t promise instant results or magic fixes, but they give you something equally important: clarity. By helping you confirm ovulation, understand your cycle, and recognise your fertile window, Tempdrop can make the difficult process of trying to conceive a little less overwhelming. Why cycle tracking matters when you're trying to conceive Most people are told the basics: have unprotected sex regularly when you're trying to conceive and you’ll get pregnant within a year. For many, that’s true. But when it doesn’t happen, it’s natural to start wondering: Am I ovulating? Are my cycles regular? Is there something I’m missing? That’s why cycle tracking is so valuable when you’re trying to conceive. It doesn’t just help you know when to have sex; it also gives you reassurance that your body is doing what it’s supposed to do, or early clues if it’s not. With a tool like Tempdrop, you can: Confirm that ovulation is happening each month Identify your actual fertile window (not just the textbook version) Notice irregularities that might be worth mentioning to your doctor later Feel more in control during the waiting period The Challenge of the Two-Year Wait In the UK, if you’re under 35, you’re usually advised to keep trying to conceive naturally for two years before getting a referral for fertility testing. For those over 35, the timeframe is shorter (usually 12 months). But either way, it can feel like a long time to wait when month after month goes by without a positive test. During this time, cycle tracking with Tempdrop can give you peace of mind. You’ll know whether ovulation is happening regularly, and if it’s not, you’ll have reliable data to bring to your GP sooner rather than later. Even if everything looks normal, Tempdrop offers reassurance when you're trying to conceive: you’re not “missing” your fertile days, and you’re giving yourself the best chance possible. How Tempdrop Works for People Trying to Conceive Traditional basal body temperature (BBT) tracking can be tricky when you're trying to conceive. You’re supposed to take your temperature every morning at the same time, before getting out of bed, and log it manually. That’s tough if you’re working shifts, travelling, or just want a lie-in. Tempdrop makes it easier. You wear it on your arm overnight, and it automatically records your temperature while you sleep. The app smooths out any variations caused by restless nights or inconsistent wake-up times, giving you a clear chart of your cycle. For people trying to conceive , that means: No stressful morning routines Reliable confirmation of ovulation A bigger, clearer picture of how your cycles are working Tracking Ovulation with Tempdrop When Trying to Conceive When ovulation occurs, progesterone rises and your body temperature shifts slightly. Tempdrop picks up this change, showing you whether ovulation happened and when. This is crucial when you’re trying to conceive , because it confirms whether you’ve actually had a fertile cycle. Over time, you’ll start to see patterns: How long your luteal phase (time between ovulation and your next period) lasts Whether your cycles are consistent or irregular Which days of the month you’re most fertile This kind of knowledge can make all the difference in how you approach trying to conceive . What if You're Not Ovulating Regularly One of the most stressful parts of trying to conceive is not knowing whether there’s a problem. With Tempdrop , you can spot if ovulation isn’t happening regularly—or at all. That doesn’t mean you won’t get pregnant naturally, but it’s useful information for your own peace of mind. And if you do eventually reach the point where you’re referred for fertility support, having months (or years) of tracked cycles can help your doctor understand your situation faster. Instead of starting from scratch, you’ll already have valuable data to share. Emotional Support while Trying to Conceive Let’s be honest: the emotional side of trying to conceive is often harder than the physical side. Each month can feel like a cycle of hope, disappointment, and pressure. Having tools like Tempdrop doesn’t erase those feelings, but it can give you back a sense of agency. By knowing what your body is doing, you avoid the endless “what ifs.” You can feel confident that you’re identifying your fertile window accurately, even if it takes time to see that positive test. Practical Tips for using Tempdrop While Trying to Conceive Be consistent – Wear your Tempdrop every night for the most reliable data. Track other signs too – Cervical mucus and cycle length are useful alongside your temperature data. Be patient – It may take a few months of data before patterns emerge. Share your charts if needed – If you eventually see a doctor, your Tempdrop records can provide a helpful starting point. The Bottom Line If you’re in the early months of trying to conceive —or even if you’re approaching the two-year wait for fertility support—using a tool like Tempdrop can help you feel less powerless. It won’t guarantee pregnancy, but it will give you the knowledge, reassurance, and confidence that you’re doing everything you can during this chapter. And sometimes, that clarity is exactly what you need to keep going. Because when it comes to fertility, knowledge really is power—and Tempdrop gives you exactly that.
