Is my vagina normal???

Hi so I’m incredibly embarrassed to be asking this at 17 years old but I’ve never had any sexual education everything I’ve learned has been from google.

Basically I think I might have a micro-perforate hymen- however I have no one to ask because I’m incredibly embarrassed and vaginas aren’t something anyone talks about.

Whenever I hold up a mirror to look at my vagina it’s all blocked and there’s no hole at all however when I push a little outwards with my lower pelvic muscles a slight hole behinds to appear at the side it’s about the size of just bigger than a pea. (I’m wondering are you supposed to see a hole without pushing it??) Ive been having issues with my vagina and I feel like blood is blocked there so this is why I’ve begun to think this. However I don’t want to tell anyone until I’m sure so I won’t be laughed at if this is normal!
