Help! Me and my boyfriend had protected sex using condoms that were up to date and also checked before putting on, he didnt ejaculate or anything while he was inside. We also tested the condoms after use for leaks by running water inside it, there was none. I also took the morning after pill the next morning. A week later I had 1 day of light spotting. My period is now 1 month overdue and i have been gaining weight! No other symptoms. Help!
