Hi my name is Pat

I am going to a gynecologist I have been told by my family doctor to have myself checked out because she found a polyp in my vagina. Why/how do you get them? What should I be asking the doctor
? Like if she says they are fine to leave are they? how do they make me feel, Meaning? I didn't know I had one.

Anything you can tell me would be very helpful. little scared....
