I got my period may 24th after that On jun 16th i had protected sex without ejaculation for about 2 minutes because I wasn't feeling comfortable. On jun 26 I got my period again I it ended July 1st , I had sex with this other guy ( now my boyfriend) all those days without protection. Now I'm 17 weeks pregnant, due date April 2 2018 , is there a possible way this baby could be the first guy from jun 16 ?
