I Recently had sex with my boyfriend and it was unprotected, he did NOT finish in me, and he ALWAYS pees before the last time he finishes. He is also very certain that if he feels the finishing pleasure that he stops. But my period is now 2 days late and I'm starting to get worried. Normally my period starts 21 days after the last one and now it's been 23 days. We had sex about 9 days ago. Please help. I'm scared and I knew I needed to be smarter about this. But I am also not having any symptoms as of yet.
