Can I get pregnant if I have sex with a man on my period?
Yes, it can happen. It is possible for a woman to get pregnant from intercourse during her period, especially if her menstrual cycle is brief.
It is also possible that a woman may think she is having her period when she is not. It is also possible to get pregnant during breakthrough vaginal bleeding.
It’s not only women with short cycles who need to be careful about unprotected vaginal intercourse during menstruation. Even when cycles are long and regular, ovulation may occur on different days in different cycles.
