Monday of the 3rd week of June I had unprotected sex. The next day I took the Next Choice pill. After taking the pill, about 7 days later, I began bleeding as if it was my menstral cycle. Over the next 2 weeks, I began experiencing cramping, weight loss, loss of appetite, sore nipples, and stomach pains, however, no nausea or vomitting. Now, I am getting scared and anxious because I have not had my menstral this month. What should I do?
