My OB's office called to tell me my due date was changed from March 9 to March 19. I had an ultrasound on August 22, which estimated to baby to be due on March 9, and estimated me to be 11 weeks 4 days then. I have to wait until October to discuss this due date change with my OB, so I am wondering if any of you think it is unusual for the OB to add 10 days to the ultrasound's estimate?
There's nothing else I can think of as to why it was changed other than just a typo. My lmp was May 28 and I had a positive home pregnancy test on July 1. My lmp points to a March 4 due date, and since I am breastfeeding, I think March 9 is right. If anyone likes the math and such, I'd love to hear your opinion :)
