100% SCREWED

STORY TIME: So the last time I had unprotected sex was on the 28th of October with a guy I barely knew & I was indeed Ovulating at my highest. Stupid of me I know but I really didn't think anything was going to happen because we barely started talking. The next day he pretty much told me to fuck off because he didn't want anything serious. Well I've had me suspicion of being pregnant and I usually get cramps a week before my period and it never misses. I'm now 2 days away from my period with no signs of my period coming, which is totally unusual. Is it really possible that I could be pregnant??
