Lump inside vagina

So TMI, proceed with caution.

I was removing a tampon today and I noticed a cherry* sized lump inside of my cooch about two inches in.

I haven’t noticed it before, and it’s not just like a half lump. It’s almost as if it’s a little ball attached to something, like this.

It’s sticking out from the stomach aimed toward the back, if that means anything.

Someone please help, I’m terrified that I’m dying with cancer because I’m an overthinker lol
