I had my first Mirena inserted in 2006 and everything was going great until about 6 months before it was time to have it changed. I gained 20 pounds in 6 months which is so crazy! I always had a good metabolism and could eat anything I wanted. So last week I had the old one removed and the new one inserted. 6 days later and I've already lost 4 pounds. So do you think the hormones changed or what?
go to the doctor
