Plastibell Circumcision - Fell Off Early

**Update** doctor said it was normal and they're not concerned. They said if it looked bad or was bleeding a lot to bring him in, but they said 3 days is ok for it to come off. Just need to live it up with aquaphor. :)

So we got our son circumcised with the Plastibell Ring on Friday. It is Monday at 230am and I go to change him and the ring is loose in his diaper. Majority of what I've found online says it takes approximately 7-10 days to come off.... Well his took 2 1/2 days.... I read on one page that it can't come off too early. He penis looks ok, but still concerned. I'm going to take him in tomorrow just so they can see it to be certain it's alright.

Has anyone else had this procedure done and if so, when did the ring come off?
