Vagina bumps?

Tori

I just got off my period , and for the past two days my vagina has had tiny itchy bumps right where the actual hole is. I am a virgin. It has a old blood smell but I’m guessing bc I just got off my period. Also dark brown discharge but I’m guessing also bc I just got of my period. Help plz I’m suuuuppppppeeeeerrrrrr confused!🤕😤🙄
