My boyfriend and I have been together for eight months, last month we had unprotected sex. He didn't really come inside of me we just kinda messed around and it was only for about a minute or two. Well about a week after we did it had my period but it was lighter than usual. But still kinda heavy. But now my period is late. And i've been really sick since than. And i've had a lot of extra discharge. Am i pregnant?
