31 weeks and Last night I went pee then got in the tub, I washed my body and hair rinsed and drained the tub, I filled the tub up again to my belly button, and after a few minutes the water wasn't clear.....it was kinda cloudy with white flake pieces in the water....after I got it off the tub I kept feeling like I had to pee and would sit on the toilet and nothing... Also had lower back pain and a little cramps, woke up this morning and was hurting so bad I couldn't move my lower back hurt and my stomach was rock hard and tender to the touch but now it don't hurt terribly, ate a bite and feel nauseous and like I'm going to throw up....any ideas
