I haven't been feeling well since last night feel like vomiting. My back hurts and stomach like menstrual cramps but not really cramping. With my other kids I always just felt sick never had tightening contractions. I went into preterm with contractions a couple weeks ago they stopped. I'm not sure how to tell if it's baby pushing unless I can feel a part of him or if it is a contraction. He's big so when he pushes it tightens everything I think
