So im 37 weeks.and ive been feeling extremely strange today ive been having pains down there throughout the whole day pain runs from my butt to my back its been coming and going, its hurts to sit, lean forward,and lean back, I been really nauseous, my hands have been falling asleep throughout the whole day, and my stomach has been getting really tight throughout the entire day, and I recently started getting dizzy. What is going on should I call labor and delivery? Or wait until Monday for my appointment?
