What effect does perimenopause have on fertility?

In the perimenopause period, just because menstruation is irregular does not mean the woman is infertile. A woman can still be fertile and can still get pregnant during perimenopause, the time period when a woman's menstrual cycle becomes irregular. In fact, many unplanned pregnancies occur in this age group of women. Menopause is not official until a woman has gone 12 months without a period.
