Tmi but anyone else?

Okay this is super gross but I’m dying to know I’m not alone. This pregnancy I haven’t really been constipated so far which is great but here’s the thing..... even when I’m done going, I can never get my ass clean. I seriously wipe over and over and I will think it’s finally clean only to find skid marks in my underwear the next time I go to pee or something. It’s disgusting and I don’t know what to do about it but surely it has something to do with being pregnant because I’ve never had this problem before. Anyone.....???
