Its not any horrific pain, and it comes and goes as a kind of...shooting pain, and it feels very low, like where my cervix is. I'm just wondering if its normal, just the baby's head knocking?

I'm 36w4d, all effaced, 2cm dilated, and baby is active and engaged. I've been doing the kick counts and everything, so i'm sure its all nothing, but you know how easy it is to worry about the baby!
