Girls, has anyone had this? I've been sitting for three days and feel nauseous, two days have been feeling queasy, my stomach hurts, but it doesn't seem like contractions, when I walk or sit down in the crotch area it feels like a ball is there, I have no strength, I want to sleep, but I can't sleep at night either The little one moves as if not herself, can't find her place I think that if I start giving birth, I won't have any strength left. I feel like a liquid jelly???
