Your baby at this time is considered full-term, and childbirth can begin at any time. The results of the ultrasound will help the doctor to outline the tactics of childbirth: you need to find out how the child lies, whether there is an entanglement with the umbilical cord, and if so, what type it is. At 38 weeks, the head of the baby descends to the entrance to the small pelvis. If the doctor saw this during the study, do not hesitate: the bill goes for days, or even hours!
