My ex boyfriend and i haveb been having unprotected sex for 5 months and i didnt get pregnant. So when i went to college we broke up and i dated another guy and had sex with him in that 5th month but it was only one time and i found out i was pregnant a week later. Does this mean that my ex boyfriend was infertile because i mean whenever we had sex it would be 3-4 times a day for those 5 months and i never got pregnant. but all the sudden i go to college and get pregnant after sleeping with a guy for one night.
Hi, and thanks for your medical question on eHealth forum!
It could be that the previous guy was infertile. It could also be that antisperm antibody generated against his sperms in your vagina were strong enough to prevent fertilization. It can depend on a number of other factors too. However, yes, chances are there that there was some problem with the previous guy. Hope this helps. Take care!
