birth control
"I've had the Mirena IUD for four months and so far it is great.  I tried it, despite many 'horror stories' because I am having trouble finding a doctor who will sterilize me (under age 30).  The insertion was very painful. I took several ibuprofen and was given misoprostol, but it only took about 10 minutes total.  The following 2 days I experienced some cramping.  After that, I've had no discomfort at all.  I don't get periods anymore and have not experienced any of the hormonal side effects described except a slight increase in body fat."
