Okay, so I lost my virginity Friday night. I was supposed to start my period like Wednesday, but I'm on the pill and it's shortened my period to about 3 days. He didn't use a condom, but he pulled out a lot and didn't cum inside me(as far as I know). My period came Saturday, but it only lasted like 2 days. And I know that sperm can possibly live inside you for up to five days. Should I be worried!?
