Can you get pregnant during perimenopause?

Irregular or skipped periods can make it feel like fertility has already ended, but perimenopause is defined by changing cycles, not absent ones — see perimenopause vs. menopause for the exact distinction. Ovulation can still happen, just less predictably, throughout the early and late menopausal transition — pregnancy remains possible right up until menopause itself is confirmed, which only happens after 12 consecutive months without a period.

Why this surprises people

Several things make pregnancy risk easy to underestimate during perimenopause:

• Skipped periods can look like menopause has already arrived, when a single long gap doesn't meet the 12-month bar that actually confirms it.
• Symptoms overlap. Fatigue, breast tenderness, nausea, and missed periods can all occur in both perimenopause and early pregnancy, which can delay recognizing either one.
• Fertility declines gradually, not suddenly — there's no clear point during the transition itself where pregnancy becomes impossible, only the 12-month confirmation of menopause.

What to do about contraception

NICE guideline NG23 recommends that people with menopause-associated symptoms be given information about contraception, specifically pointing to dedicated UK guidance on contraception for women over 40. There's no universal date to simply stop — the right answer depends on your age, your contraceptive method, and your personal health history, which is exactly the kind of decision worth making with a clinician rather than guessing from symptoms.

If you think you might be pregnant

A home pregnancy test is a reasonable first step if you've missed a period and aren't sure which explanation fits. If it's positive, or if you're unsure, contact your clinician promptly — some medications and treatment decisions differ depending on pregnancy status.
