Contraception is personal. The right method is the one that fits your health, your priorities, your tolerance for side effects and how strongly you need to avoid pregnancy.
World Contraception Day is a useful moment to look beyond the idea that one method is “natural” and therefore automatically better. Fertility awareness can be a valid choice for some people, hormonal contraception can be the right choice for others, and barrier methods have their own important role. Good contraception is about informed choice, not ideology.
What Counts as Natural Contraception?
Natural family planning, often called fertility awareness, involves learning the signs of fertility across the menstrual cycle. Depending on the method, this can include basal body temperature, cervical mucus or vaginal discharge and cycle dates.
The NHS advises learning natural family planning from a trained practitioner. When followed correctly all the time, it can be 91% to 99% effective. If the instructions are not followed carefully, effectiveness is around 76%. It does not protect against sexually transmitted infections.
What BBT Can and Cannot Tell You
Basal body temperature rises slightly after ovulation because of progesterone. That makes BBT useful for confirming ovulation retrospectively. It does not reliably tell you, in advance, that ovulation will happen tomorrow.
For pregnancy prevention, BBT should not be treated as a stand-alone contraceptive signal. Established fertility awareness methods use specific rules and often combine more than one fertility sign. If you want to understand the temperature side in more detail, read our complete BBT tracking guide.
A Balanced Look at Hormonal Contraception
Hormonal contraception has benefits and risks, and those vary by method and by person. It can make periods lighter or more predictable and is used for contraception as well as conditions such as painful periods, acne and some gynaecological symptoms.
It is also important not to overstate side effects. For example, the NHS states there is no evidence that the combined pill causes weight gain or changes sex drive. Combined hormonal contraception carries a small increased risk of blood clots, and the relationship with cancer is nuanced: some risks increase slightly while using it, while risks of womb, ovarian and bowel cancer are reduced.
If you are deciding whether the pill is right for you, your medical history matters more than a blanket claim that hormones are either good or bad. The NHS explains the combined pill's side effects and risks here.
The Main Options at a Glance
Fertility awareness
Tracks fertility signs and requires consistent learning and daily attention. Does not protect against STIs.
Condoms
Barrier contraception that also helps protect against STIs. Effectiveness depends on correct use.
Hormonal methods
Includes pills, patches, rings, injections, implants and hormonal coils. Benefits, risks and suitability differ by method.
Non-hormonal long-acting contraception
The copper IUD is highly effective and hormone-free, but can make periods heavier or more painful for some people.
If preventing pregnancy is particularly important, discuss your options with a pharmacist, GP, sexual health clinic or contraception service so you understand typical-use effectiveness as well as side effects.
Natural contraception: common questions
What is the best natural contraception method?
There is no single best method for everyone. Fertility awareness can suit people who are able to track consistently and are comfortable avoiding unprotected sex or using barrier contraception during fertile days.
How effective is natural family planning?
NHS guidance says fertility-awareness methods are estimated to be 91% to 99% effective when followed correctly all the time, but around 76% effective with typical use.
Can BBT be used as birth control on its own?
BBT is mainly a retrospective sign that ovulation may already have happened. Natural family planning methods generally use more than one fertility sign and are best learned from a trained practitioner.
Does natural contraception protect against STIs?
No. Fertility awareness does not protect against sexually transmitted infections. Condoms are needed for STI protection.
Informed Choice Is the Goal
There is no prize for choosing the most “natural” method, and there is no obligation to stay on a hormonal method that does not suit you. The best decision is one made with accurate information about effectiveness, benefits, risks, STI protection and the amount of daily attention a method requires.
If you are interested in fertility awareness for body literacy rather than contraception, our fertility and ovulation tracking collection brings together tools designed to help you understand cycle patterns. Tracking technology itself should not be assumed to provide contraceptive protection unless it is specifically regulated and used according to its instructions.
