Quick read
Key points
- 1
Contraception is still needed during perimenopause, since pregnancy remains possible until periods have fully stopped, even as fertility naturally declines. Current guidance generally recommends continuing contraception until 12 months after your last period if you're over 50, or 24 months after your last period if you're under 50, since periods can become irregular for a long time before stopping completely.

What is Contraception and Menopause?
Contraception is still needed during perimenopause, since pregnancy remains possible until periods have fully stopped, even as fertility naturally declines. Current guidance generally recommends continuing contraception until 12 months after your last period if you're over 50, or 24 months after your last period if you're under 50, since periods can become irregular for a long time before stopping completely.
Some contraceptive methods can also help manage perimenopausal symptoms, such as irregular or heavy bleeding, while others may not be suitable alongside certain menopause treatments — a doctor can help you find the right approach for your individual situation.
02 · Understand
Clinical context
Irregular periods don't mean you're not fertile
Even with irregular periods during perimenopause, ovulation can still occur unpredictably, meaning pregnancy remains possible until the recommended contraception-free timeframe has passed.
