I'm starting to freak out...my period was due yesterday according to this app. I have no one symptoms of it coming though. I had sex a few times this month, but we used a condom each time and I don't believe any of them broke or slipped. I checked the condoms for leakage after he was done in each one and no holes were found...im still scared though...has anyone else had this happen to them? idk why else my period would be late..but I also dont get how i could be pregnant when we used condoms from start to finish and used them right.
