Me And My Husband Had Sex During My Period And
Pregnancy would be very unlikely
Hello, I'm Dr. Branch, thanks for using 'Ask a Doctor'. Depending on when you had your depo shot, it can still be effective for a few weeks after you are supposed to get another shot, so there is a good chance it was still effective when you had sex. Also, if you were having your period at the time of sex, pregnancy would be very unlikely, both because of the blood which would interfere with the sperm travelling to the uterus, and because it would be unlikely you would ovulate shortly after this in order to be able to get pregnant. You can check a pregnancy test 2-3 weeks after the last time you had sex to make sure, but I would expect that it will be negative.
I hope that helps, please let me know if you have any other questions about that, and I would be glad to discuss it with you further.
