So I got checked for dilation on Tuesday and the doctor told me I have a cyst right on the inside of my vagina. I was wondering because whenever I sit up I feel like a popping but I thought it was just pregnancy. That's the only time I ever notice it. Should I be worried??? Has anybody ever had this happen? Also will it affect delivering her?
