I feel like this is way too early for me to be getting this... but I have horrible crampy/achy pain in my lower back and pressure downwards near my rectum and sacrum. It hurts whether I stand up or lay down. I thought maybe I wasn't drinking enough water, or was constipated, but even drinking a lot of water or after going to the bathroom it still hurts. I did not have any of this with my first pregnancy. Anyone get anything like this during the second tri?
