Question: The morning after pill & menstrual cycle

 Nichole03 - Thu Apr 30, 2009 3:18 pm

I currently took the morning after pill a day after having unprotcted sex around the 18th or 17th or april. It has been maybe a week and a half and at first my discharge seemed to be little to none. Then it appeared normal as usual, but now it has turned a light brown. It has been this way for a few days. I have pain in the left side of my hip...? And when I go to use the restroom I have a hard time pooping, but before I had trouble, I had diarehha...My period isn't due until around the 9th of May but my cycles usually are irregular occurring a few days before or after the "scheduhled" time. I'm wondering if the morning after pill could cause me to mensturate early...Or if I should grab a pregnancy test...? I know that brown discharge is a sign of pregnancy and that the morning after pill contributes to some ectopic pregnancies...? help.

User avatar Hello,
Yes, this strong hormone can definitely affect your cycle both in timing, type of discharge and other side effects. I would expect the pill to have been effective, taken soon like you did. There are many causes of abdominal discomfort and bowel-related problems such as diarrhea and constipation, with cramping, is quite common.

Ectopic pregnancies occur 6 to 8 weeks after a missed period so you can pretty much rule this out if the sexual encounter only occurred April 17-18. A home pregnancy test is usually reliable a week after the missed period.

If pain continues, you will want to have it checked out but I would not be alarmed at the bleeding. Brown blood usually means old blood that wasn't eliminated with the last period.

Best wishes.
