It doesn't really matter but I went to my weekly doctors appt today and they said I'm 35 and half weeks pregnant but according to my ultrasound I will be 35 weeks tomorrow. I'm small for where I'm suppose to be at anyways but I'm just curious. It really doesn't matter since it's only a few days different but I'm just curious which one should I believe more. (P.s this isn't new news about the difference in weeks just really curious now)
Once you have you first trimester U/S they determine your due date. It will very rarely change after that. Baby's will grow at different rates, at different times. So you go by your original due date, regardless of what any later U/S says.
