I measured small with my second and my doc told me that it can all depend on how you carry the baby and how the baby is positioned and it doesn't always have to do with how big the baby is or how much you have gained. Like some women carry more wide instead of all out front and because you are measured vertically that could make you measure a little smaller or for someone who is all out front then they could measure larger. It also depends on the baby. Like if you carry lower you might measure lager. Also I read that the way your pelvis is positioned can have an effect on how the baby lays. I know with my second I was kinda all over the place....like on visit I was measuring 2 weeks behind then the next visit right on, and then the visit after that I was back to 1 week behind. And my doc said the baby was probably just in different positions. So I don't think it has a lot to do with when the baby will come.
