I have what seems to be some kind of growth on my lower abdomen. I am 30 weeks pregnant with my 3rd child. I have never seen or had something like this before. I had a big round belly up until about 2 weeks ago, now there is what looks and feels like a mass the size of a baseball cut in half at the very base of my belly. I go to see a doctor Tuesday for a normal checkup but I want to find out sooner if I need to go in asap. It's kinda freakin me out it's also slightly discolored from the rest of my belly, almost like a loss of color actually. Please help!
