I have been in the menopause for 4 years and had a period year when is it safe to unprotected sex?

It is unlikely that you are still able to get pregnant.

Menopause is the end of a woman's menstrual cycles, which usually occurs around the age of 45-55. However, some women may continue to have periods for a year or two after their last menstrual period. This is called post-menopausal bleeding. While it is possible to become pregnant during this time, it is unlikely.

If you are concerned about pregnancy, you can take a pregnancy test or talk to your doctor.
