having really strong contractions, and I'm three days away from the original due date they gave me, I feel like if I go to Labor and deliver it would just be a waste of time, cuz my water has not broke and when I went to the doctors on Thursday I was one one cm. they did tell me that they baby is measuring big, and they wanted to order an ultrasound, if I tell that to they hospital will they due the ultrasound.
