I had unprotected sex during the time I was ovulating. My boyfriend didn't cum inside me but I know it is still possible to get pregnant off of pre cum. My period was due today (September 22) but nothing has happened and all I have is cramps like I do when I have my period. I've had cramps for the past week and thought I was gonna start then but I didn't and now my period is due and nothing is happening and I don't know what to do. My lower abdomen is tight and I stay tired. My friend is getting me a pregnancy test tomorrow and forcing me to take one so I can stop worrying about it. Could I be pregnant?I'm sort of scared...
