Sex During Menstrual Period

    Q: Can I get pregnant if I have sex during my menstrual period?

    A: Ovulation and fertilization does not usually happen until after your bleeding and your menstrual period end. But you can get pregnant if you have unprotected sex during your menstrual period because sperm can survive for up to 5-6 days, and if you ovulate within that period it's possible to get pregnant. So making love within five to six days before ovulation can lead to a pregnancy.

    When you have a short menstrual cycle, ovulation occurs much earlier than Cycle Day 14. For example, with a 21-day-cycle you ovulate on day 7 after the LMP, so making love on CD 2 can get you pregnant.

    Summary:

    Ovulation and fertilization don't happen during your period but you can get pregnant from making love during your period because sperm can survive for up to 5-6 days.
