Birth Control
"Started Nuvaring on a Sunday and by Tuesdsay I was in the emergency room with  severe abdominal pain, back pain, and headaches. The emergency room could not find anything wrong with me so on Wednesday I was back at my primary care doctor. I was previously on Sprintec and clearly that worked better for me because I had no side effects. My doctor said I had an allergic reaction to the hormones in Nuvaring. It is convenient which would have been nice since I am going to college in the fall and it works amazingly well for my sister. Regardless, make sure that you change birth control immediately if you begin having any side effects because it will probably only get worse."
