I was raped about 3 1/2 weeks ago... I had been on birth control for a few weeks before them, but only on a low dose. Since Saturday, I have been extremely sick to my stomach on and off all day. I feel like throwing up soooo bad! I have had a bad headache and I feel a full feeling in my stomach.I feel these weird feelings to the left and right of my belly button. I cramped real bad for a while. I had my period the week after it happened. I'm very easily irritated too... Is it possible?
