birth control
"I read a lot of horror stories online before I got the Mirena so I was concerned, but willing to give it a try. I think it's great - but there were a few bad points in the first few months of the medication. 

Insertion was very uncomfortable, cramping followed by cramps lasting for six hours and light soreness for a couple of days (I have no children). I had a light period lasting for over one month after insertion, and really weird brown discharge after that for several months. I didn't notice a change to my libido. I felt "aware" of the Mirena for a while. But I stuck with it. 

It's a year since. I have no symptoms - no mood swings, no skin issues, no weird bodily functions. I don't have a period anymore or any cramping - it's awesome!"
