wtf vag and period.

I'm not a virgin so my himon is broke. I dont know how to spell it but lets leave it like that. Anyways, i use tampons and it doesn't happen all the time but my string gets looped inside of were it broke and when i pull my tampon out, i can't because it hurts and i have to spend 5-10 minutes trying to pull the string through while my fingers are all up in my blood and its gross. Is this normal? I don't think it is. Becase my mom has no idea. HELP!
