Hello everyone! Yesterday I had an ultrasound, my due date was supposed to be 35.6 weeks, but on the ultrasound they said 36.6 weeks. They looked at it with two doctors, the second one was called later to make sure. The baby's weight is 2800 grams and he has already turned his head down. This is the third time I have done an ultrasound, and the dates always matched, but now it turns out a week earlier. Doesn't this mean that our boy will be born before the EDD? My husband is worried, and relatives have already started packing their bags for the hospital ? Has anyone had something similar where the ultrasound shows a longer date than the menstrual
