I know I asked this the other day, but I'm 30 weeks & I keep getting pelvic pain. It hurts to move or stand up or walk. It's more of a pain than pressure, but I do get the feel the I have to poop when I don't. I called my doctor and waiting for them to call back, but I'm kind of worried, should I be?
