emergency contraception
"It does what it is supposed to do - I didn't get pregnant. However, I took it two months ago (Sept 21) and I'm still seeing side effects. I've always had very mild periods with PMS symptoms starting about a week prior. Now my periods are crazy heavy and the cramping (which is much worse and more painful), feeling sick, tiredness, and breast tenderness starts two weeks before my period. I hope eventually my body will get back to normal but so far I've seen nothing but bad side effects from this medicine. Keep in mind, I'm 5'4 and I weigh 120 lbs and being small may have something to do with it. Also, I usually don't take medication and have never been on birth control because of bad side effects."
