hi, I have a bump next to/below my cervix on the back vaginal wall. It feels like it is some sort of bump inside my body that i can feel rather than on the wall itself. I got an ultrasound and have no cysts, and saw two obgyn's and they could not feel it and told me not to worry. It sort of feels like an egg and I am wondering if it could be one side of my uterus, a ligament, or a muscle. I have a slightly tilted uterus. Could it be one side of my uterus that I am feeling? (that is what one doctor suggested)
