I had unprotected sex just a stupid mistake that happened with an ex boyfriend the day before I started my period.. had a normal period.. lasted 5 days then I had sex with my current boyfriend a day after my period and a few more times! Please don't judge I'm just looking to help ease my feelings. Well took a test July 4th and it came back positive... I ovulated about 8 days after my period and the Dr. says my conception was around the 17th.. I guess my question is.. I couldn't have gotten pregnant before my period and have it be m y ex's right?
