It's not always easy to conﬁrm that the menopause has actually happened. Irregular periods and hot flushes are a sign that changes are taking place, but identifying the time of the actual menopause is not simple. Even though your monthly periods are not regular anymore, you can still get pregnant. In fact, the irregular periods common in menopause, makes it harder to predict when an ovary is releasing an egg - the time when sex is most likely to result in pregnancy.
It is helpful to know the date of your last period, for contraceptive purposes. A truly postmenopausal woman will be infertile and will have no need of contraception.
Most doctors advise menopausal women under 50 to continue with their contraception for two years after their last period and for one year if they are over 50. Do speak to your healthcare professional for contraception and menopause advice.
