Hi. I have an issue. I have my boy friend and then there was my ex. My boy friend we have sex almost everyday unprotected and he never pulls out when he's done and the year that we're together I haven't gotten pregnant. Mind u I was smoking pot everyday sometimes 2-3 times a day. I didn't get pregnant. Now two days after my pd is over I had sex with an ex only ONE time and my boyfriend a few times in the same week. About Four- five weeks after that, I'm late I take a test It's Positive!!! I'm happy but not too happy knowing it can be my ex.. What is the possibility it is my ex who got me pregnant??? PLEASE HELP ME!!!!!!! thanks!
