One of the most common questions women in their 40s ask: can I still get pregnant during perimenopause? The short answer is yes — and many women are surprised to find out just how long they need to keep using contraception.
⚠️ ⚠️ Key fact: Ovulation becomes less frequent during perimenopause, but it does not stop until menopause is reached (12 consecutive months without a period). Until that point, pregnancy is possible.
Why Pregnancy Is Still Possible
During perimenopause, your ovaries are still releasing eggs — just less predictably. Because your cycles become irregular, you may not know when (or if) you are ovulating in any given month. This unpredictability actually makes it harder to avoid pregnancy by tracking cycles alone.
How Long Do You Need Contraception?
Australian clinical guidelines recommend continuing contraception until:
- Age 50 and 2 years after your last period, OR
- Age 50+ and 1 year after your last period
If you are under 50, the recommendation is to use contraception for 2 years after your last period. Over 50, it is 1 year. This accounts for the possibility of a late ovulation even after a long gap between periods.
Contraception Options During Perimenopause
Not all contraceptive methods are equally suitable during perimenopause. The combined oral contraceptive pill (containing oestrogen and progestogen) can mask perimenopause symptoms and is generally not recommended after age 50 due to cardiovascular risk. Options that work well include:
- Progestogen-only pill (mini-pill)
- Hormonal IUD (Mirena) — also helps with heavy periods
- Copper IUD
- Condoms
- Sterilisation (tubal ligation or vasectomy)
If You Want to Conceive During Perimenopause
Fertility declines significantly during perimenopause, but conception is possible, particularly in early perimenopause. If you wish to conceive, speak to your GP as soon as possible. They can refer you to a fertility specialist who can assess your ovarian reserve and discuss options including IVF.
The Emotional Side
For women who did not want more children, discovering they still need contraception can be frustrating. For women who hoped to conceive, the declining fertility of perimenopause can be devastating. Both experiences are valid and deserve support. Your GP can help you navigate whichever situation applies to you.
