birth control
"I went on this BC because I do not get regular periods, usually just random light spotting. I wanted something to regulate it. I started it and 3 days later got the worst period I've ever experienced. Lasted 10 days (I stopped the pill after 7 days) with heavy bleeding and severe abdominal cramps, very clotty. Lost my appetite and got acne in places I've never had it before, like my back and chest. After that period ended I decided to give it another try. Exact same experience as the first time as well as nausea, vomiting, dizziness, lightheaded and constipation. Stopping it immediately and going back to my doctor."
