Yes, I have to say I am very confused about this cm=weeks thing. And pretty sure at this point that it's total BS, because where I live they don't expect the cm to match weeks *at all*. Last week at 36+3 I measured 34.5 cm, and that was a generous measure (the first time she measured she got 31.5 cm - that in itself should say something). If I were to have measured 36+ cm, it would have been outside of the little "average" curve on my chart, and I would have been "measuring ahead". As it is I've been right in the middle of the "average" curve this whole pregnancy, but apparently in the US I would have been measuring "behind" the whole time. Apparently they have different standards here. So I've just gotten SO skeptical about the fundus measurement at all.
