Girls, it's week 37. This is my fourth delivery. I learned about Braxton Hicks contractions in this pregnancy. And generally, all the signs are already there. Today started to prickle specifically in the uterus. Like needles and noticeably so. What is that? I have never experienced this before. It's exactly in the uterus that it pricks.
