When mine went AWOL I had to have a scan and they couldn't find it anywhere. The Dr decided that since I suddenly had a heavy period after ages with no period it must have fallen out. Kind of embarrassing to think that something that size could fall out without me even noticing

One of our members had to have their removed under a GA after it went AWOL because it had moved up into the side of her uterus.

I hope yours is easy to find.
