Opening after birth... TMI

Amy
So I have my 6 week apt tomorrow and have felt great! No pain down there and really felt like I recovered great but last night i decided to look down there just to check it out. I noticed that there is something inside my vagina blocking the hole. It's like there is no hole anymore...!!! I did some googling and am thinking it may be a prolaps but did anyone else have anything like this after childbirth?!
Info: I'm 29 and Had an 8lb 11oz babe and she came out after 11 mins of pushing. She is my first. Only a second degree tear but had quite a few stitches as they couldn't get one area to stop bleeding.
