birth control
"I am on my second Mirena - I had the first one for the full 5 years and loved it. I want to caution about one thing that has not been mentioned in any of the posts I have read.  After the first Mirena my new doctor insisted on an ultrasound before replacing it with a new one for 5 more years. I am grateful she insisted. I had 2 strawberry sized cysts - one on each ovary.  Easily treated with 3 months of birth control. The cysts disappeared and I was able to have a new Mirena. This insertion was very painful. In the hour afterwards I broke into a sweat and almost passed out. It has been 2 days and I'm much better, just light cramping.  Please get an ultrasound before replacing.  My doctor will also require follow up ultrasounds in 2 years."
