Oh my goodness i've been getting the exact same things!! I'm 40wks too, have had plenty of BH and am waddling like duck with a watermelon up its butt....no show yet, but lots of extra mucous. I figured it was just the head engaging further into my pelvis...but you're right....it hurts like crazy and you think you're pubic area is splitting in 2! I swear i can feel the baby's head and hands squirming down there. We just have to hang in there GKD....it can't be too long now!!!
