movement of port

I had my surgery on July 31 and have lost 82 pounds but recently I have had my port move. It is pointing out of my skin. The first time it happen it felt like a pop and then I was looking at and could really see it. I told the dr but he said he had never heard of it. All I have to do is push on it and it goes back in place. Has this happened to any one else:confused:

sounds like one of the corners came un-stitched.
