Re: Gestational Age Question
My midwife told me that the earlier the more accurate-like within a couple days. She said that as far along as 18 - 20 weeks or so it could be off by a couple weeks. It makes sence because the baby really starts to grow rapidly in the 5th month, but in the beginning the growth is small, and it seems that most embryo's start off about the same. Remember that only 1 out of 20 babies are born on his or her due date. I don't know what you should do regarding changing it or not. Some people who say their baby was a week late or early might have just been off on their due date. Anyway it's interesting, and I hope someone can give you a better answer than me. Good luck. I can't wait til I'm at 18 weeks!
