Ok, so my period is support to start within the next couple of days. My bf(25) and I(18 almost 19) had unprotected sex a day before I began ovulating. And this past weekend we had unprotectted sex multiple times and he came 3x. I am curious to know if my period may still start and if there is a chance I may be pregnant. Honestly, I wouldn't mind being pregnant right now and having a baby with him. Neither would he. The hard part is my family and the fact that I am graduating high school in 57 days.
