Levonorgestrel
birth control
"I've had the Mirena for almost 3 years now. Insertion wasn't a problem. However, at my next annual exam my doctor told me he didn't see the string anymore but assured me it's not a problem. I had spotting each month in the beginning. Very light and would last about 3 days. I also experienced heavy discharge in the beginning. Now I have no spotting, no discharge. I did gain weight from it. Lately I have been experiencing severe cramping which I can only describe as almost feeling like contractions when you're about to give birth. They're that bad! Needless to say, I have scheduled an appointment with my OBGYN and I may have it removed. But overall, it's an effective birth control."
