I’ve never heard of it, but I read up on it just now and supposedly it’s most common in late child bearing years . It’s odd since you are so young and your Littles are still little , so your uterus has functioned to carry them. I’d definitely get a second and third opinion, but I think if it wasn’t going to cause any life threatening or terribly painful problems I’d avoid getting my uterus removed . Doctors are wrong all the time and sometimes miracles happen.
