Is this normal?

I’m 15 years old, I’m a virgin and I have never used a tampon or masturbated. I wanted to explore my body, locate my cervix and just have an idea about my body.

I can’t see my vaginal opening but I manage to enter my finger, when I go in there’s this sort of bone I guess in the beginning it’s really weird, I go under it and then it feels hard from above but softer from the sides and down and it feels like I’m going towards my asshole or something it feels really weird. I also can’t feel my cervix so I’m guessing i have a high cervix but I’m also worried that this hard thing in the beginning is my cervix because if it is then I’ve got a very low cervix I barely have the tip of my finger in. I also couldn’t enter more than one finger which I’m guessing is alright since I’m a virgin

I’m not sure if any of this is normal specially this hard thing near the opening

**edit

What I’m asking is if what I’m feeling inside is normal
