Ethinyl estradiol / norgestimate
"When first taking this medication, I threw up the first few days of taking it. Through the months I have experienced excruciating pain 2-6 hours after taking it. I normally take it around 11 or 12, right before bed. so between 1 and 6 in the morning, I am waken up by the pain. It's an aching pain with nausea. it is about once or twice a month, but when it occurs, it is unbearable! It lasts for about an hour or until I can fall asleep in the fetal position (the only thing that lessens the pain.) I am not allergic to anything nor sensitive to foods, so I am sure it is not related to consumed foods. It does have some positives. I  ALWAYS receive my period on the same day and am not pregnant. So it does what it was intended for!"
