birth control
"It is effective, I have had it for 11 months and at first I didn't have my period for the next 3 months after the first month of having it, I thought it was great. After that I had my period every 2 weeks if not every other, cramps, headaches, and mood swings. It had been a horrible experience. The weight gain since I have had it in was 30 pounds. I weighed 132 lbs. a year ago and now I weigh 165 lbs.! I haven't changed my eating habits or working out habits. I love to run and the weight gain has taken a negative toll on it. I definitely do not recommend. 5'7 medium frame, always have been thin"
