So my OBGYN told me my due date was July 18th at my first appointment a month ago. Yesterday, I went to the ER over pain and pressure. They did an ultrasound and the baby is measuring at 14w4d and the ultrasound tech said my due date is July 12th now. I had an appointment with my OBGYN today and she didn’t say anything about it. Should I stick with the original or what my doctor originally gave me? TIA
