My boyfriend and I had last had sex on January 31....I'm was supposed to get my period around feb.8th.....It didn't come. I had a little bit of spotting.

Until I went on Vacation March 3rd....I recall it being lighter then normal...

I just got my period yesterday, first day was light, I still had horrible cramps that let me bed ridden, and headaches.

I don't feel like I'm prego, it just feels like a normal period minus the lighter flow.

Is it possible that I am prego?? Or is something else wrong with me?
