Hi has anyone had a growth scan either with this or a previous pregnancy. If so how accurate was it? I am being scanned at 36 wks as i have very large babies my midwife told me yesterday that they arent very accurate and can be a 1lb out! Im sooo scared that the scan will be wrong and they'l let me carry on til I go into labour naturally and she turns out to be massive and I cant deliver her. I really, really dont want to have to have a C-section.
