Hi ladies, has anyone had the Mirena IUD cause them to gain weight, especially in the abdominal area? I am 18 months postpartum, but I have always had a flat upper stomach. Now, it is rounded, along with the lower area. I had a c section, and I realize that some of this could be baby weight, but I do work out. I had my son at 45, which I know could be a factor, but I just need some input to determine whether or not I should have it removed. I’m tired of looking bloated. Thanks!
