Please go with the original due date. They probably won't change it anyways unless it's more than 2 weeks from your original due date (based on last cycle). Also, when you get to your 20 week ultrasound it will be more accurate, or so they say. As a mother to 8 children, and expecting our 9th, prepare yourself for the later due date. The last 2 weeks can be tough and if your baby comes 'early' (closer to the ultrasound date) then great, a wonderful 'suprise'.View Thread
