The Thyroid–Cycle Connection: Missed Ovulation, Lost Periods, and Hashimoto’s Health
Title: The Thyroid–Cycle Connection: Missed Ovulation, Lost Periods, and Hashimoto’s Health
Host: Stef Meachin
Guest: Rocsi, Founder of Her Aligned Hub
Length: ~Approx 60 minutes
In this eye-opening episode of Know Your Flow, Stef sits down with Rocsi, Founder of Her Aligned Hub, to explore the deeply intertwined relationship between thyroid health, menstrual cycles, ovulation, fertility, and autoimmune conditions like Hashimoto’s.
Rocsi opens up about her journey through misdiagnosis, cysts, burnout, and thyroid dysfunction — and how learning to understand her hormones completely shifted her health. She shares practical strategies for supporting thyroid function, managing symptoms, and restoring menstrual regularity, along with insights into nutrition, lifestyle, and mindset shifts that can make a real difference.
This episode breaks down the biology in a clear, accessible way while offering hope and direction to anyone who feels unheard or confused about their symptoms. Whether you’re TTC, dealing with irregular cycles, or navigating chronic symptoms, this conversation will help you reconnect with your body, advocate for better care, and take actionable steps toward hormonal balance.
“So many women think their cycle is broken when really, their thyroid is asking for help.”
In This Episode, We Discuss:
- How hypothyroidism and Hashimoto’s can lead to missed ovulation, long cycles, or lost periods.
- Why thyroid issues in women are so commonly misdiagnosed as PCOS.
- The exact hormones involved—and how thyroid function disrupts FSH, LH, oestrogen, and progesterone.
- Symptoms of both under-active and overactive thyroid that often get dismissed.
- What blood tests you actually need (and how to advocate for them).
- The surprising role of gut health in healing your hormones.
- Why so many women fall through the cracks - and how to take back control.
“If your doctor only checks TSH, you’re seeing 5% of the picture.”
Episode Takeaways
1. Your thyroid has a direct impact on ovulation.
Thyroid hormones play a key role in regulating your reproductive system. If your thyroid is underactive (hypothyroidism), ovulation may stop entirely, be delayed, or occur inconsistently. Even mild imbalances can disrupt the delicate hormonal signals needed for regular cycles, affecting fertility and overall cycle health.
2.Many women with thyroid issues are misdiagnosed with PCOS.
Symptoms like irregular periods, weight changes, and cystic ovaries can overlap with PCOS, but an ultrasound alone doesn’t reveal the underlying thyroid or autoimmune issues. Without a full evaluation, many women receive treatments that don’t address the root cause.
3.TSH alone is not enough to assess thyroid health.
While TSH is commonly measured, it only tells part of the story. A complete thyroid panel, including Free T3, Free T4, Reverse T3, and thyroid antibodies, plus key nutrient markers like iodine, selenium, and vitamin D, is essential for understanding your true thyroid function.
4.Autoimmunity, stress, gut health, and energy availability matter.
Thyroid function doesn’t exist in isolation. Chronic stress, poor gut health, low energy intake, and autoimmune activity all influence your thyroid and reproductive hormones. Supporting these areas can improve thyroid function and cycle regularity.
5. Missed ovulation is a common symptom of thyroid dysfunction — not a personal failure.
If your cycle is irregular or you’re not ovulating, it’s not because your body is “broken” or you’ve done something wrong. Your reproductive system is reacting to hormonal imbalances, and with the right support, ovulation and cycle health can often be restored naturally.
6. You deserve answers. You deserve to be heard.
“I was told again and again that everything was ‘normal’ but my body didn’t feel normal.”
