Is it possible to not feel stitches tearing? How can I be sure they didn’t?

So I’m 8 weeks pp and have a follow up appointment soon...but, I’ve recently looked down there, and **tmi** it seems there’s an extra little ‘flap’ of skin where my vagina is, but looking closer, it kind of seems like maybe it’s part of the tear that didn’t heal together..

I mean, of course I was in a lot of pain postpartum but there was no point where i felt I may have torn my stitches. Is that possible? Or is this just a normal change?

Again, ***tmi!!*** but while the inside of my vagina feels pretty tight, the opening does not anymore, at all. So torn stitches? Normal change? Any insight?
