I have a doctors app tomorrow, but I'm curious; I'm having sharp pains in my lady bits, at first it was when I was walking a lot, or when I reached up for something and now it's happening when I'm sitting and it'll wrap around to my back. What could it be? I haven't had any BH yet, could it possibly be that?
