weird cord like string type thing in my vagina?

This is so awkward. But. We're all friends here right? When I finger myself i can feel a loop. It feels like a piece of string. I can fit my finger right through it. It doesn't hurt to squeeze but it hurts if I pull on it so I definitely think it's attached. Should I see a OBGYN? Do other girls have this? Is this why I can't wear tampons?! HELP LOL
