Might’ve been too soon?

I had sex for the first time about 3 weeks after I gave birth and it was amazing. Then again a little over 4 weeks. It doesn’t necessarily hurt but it’s a different feeling(still good) but now my vagina feels different, I have had to feel around with my fingers to check my stitches which I believe are dissolved. There is something new exposed when I feel around tho. I’m not sure what a prolapsed uterus feels like but I’m curious if that’s what I’m experiencing because I don’t know what else it could be. I am so scared to ruin sex because it’s something I very much enjoy, but who doesn’t? Ease my mind please
