Girls this is so embarrassing

So I'm going to be doing this anonymously. But this is serious and I just want answers because honestly kinda scared to tell anyone about it because it's just embarrassing and I dont want anything bad to come out from it...

So for maybe a few months my butthole outside of it has been itching like crazy. Sometimes I can't help it but to scratch and it's disgusting. But it also hurts like if there was a cut there, like when I take a shower I try and wash it with soap and when I do it stings so bad! (But I do it anyways) but anyways I've been noticing when I go to the bathroom (poop) there is blood when I wipe and blood in my poop. And I'm not sure why.

A few months ago I got a ct done and blood test for everything and everything came back normal. Idk what's going on but I am getting super tired of it hurting and itching. Any suggestions or advice or anyone can tell me their stories would be nice... I won't be commenting... but I will post my answers on your guys comment in this post....

I'm sorry it's a gross subject I dont even wanna tell my doctor about it. How would I even go about that? I'm 19, a mom, idk what's going on. I feel fine other than this going on.

Update: thank you everyone.. it has taken bit forever to actually post this because it is embarrassing but ill get the courage to go to the doctors because it is getting annoying with having this feeling I just want it to be better. Thank you 💕
