Bruh, What Is This?

Okay so like my period ended 3 or 4 days ago and ever since it feels like there is air in my pelvis or what I assume are my ovaries lol.

I tried to like push it out but it goes from my uterus/pelvis to under my belly button. I feel like it can't come out and I know I'm not bloated so idk what to do.

I can currently feel the air or whatever it is and it sometimes is painful, which is why I'm asking the eve community. Also is this helps, I never had sex, No type of birth control, never stuck anything up there but tampons but I don't use them all the time.

So yeah, if you can give suggestions on what this is, please do!!!!
