My boyfriend and I have been dating for seven months and used a condom only twice.every time we make love he cums in me.. he's 29 and has no children so he's starting to think he's incapable of having children... I get my period on the 16th or 17th of every month but didn't get it until the 18th.. could I be pegnent or is this normal? Please answer asap.. thanx!
