I started my period on a Thursday. It stopped on a Saturday. It is now Wednesday and I am bleeding again. I have had abdominal pain a little more, and actually threw up due to being in so much pain. I don't feel pain now, but I'm wondering if my period is suppose to be like this. The only time my period usually stops early is when I have worked out, but I didn't this month. I am on birth control and am married so I'm sexually active.
