Another question, you know... I'm 39-40 weeks pregnant, my body is getting really cleaned out, diarrhea 10-12 times a day, it's harder to walk, but there are no contractions yet, in my first pregnancy, I felt contractions but I didn't feel them, only it was visible on the ultrasound... doctors were surprised, the opening was 4 fingers and water went away, I didn't feel any contractions, could that be? In my second pregnancy now I don't feel anything but it's hard to walk?
