i agree with shannon def sound like your cervix, i was worried the first time i felt mine as i didnt know it was there til my first pregnancy, dont stress unless of course it is hurting you.
Sounds like your cervix to me, which is completely normal. But you should have yourself checked by a GYN, just to be sure and for reassurance.
Yes, most likely a benign uterine polyp. They can be removed and very rarely become cancerous. Depending on where it's attached it could reduce your chances of becoming pregnant. It's probably worth mentioning to your doctor the next time you're in.
Cervical Polyps maybe? They are long, finger-like growths from the mucous layer of the cervix or cervical canal...you need to seen by a doctor though
