birth control
"I have had the Mirena for about a month. The insertion was easy and it took my very experienced ob about 5 minutes.  It honestly felt like a pap smear.  I also have 3 kids and a retroverted uterus for what it's worth. Unfortunately, I have had spotting every day since. I hope it stops soon because I have no other side effects. No weight gain, acne, etc and my sex drive has actually increased (weird right?). So if you are considering having a Mirena inserted my advice is to try it and see how it works with YOUR body. Yes, you can read the horror stories on this site and others. People are much more inclined to share a negative experience than a positive one. Talk to your doctor and look at actual peer reviewed studies."
