Just wanted to ask advice/experiences of others. I received my midwife pack yesterday and my midwife appointment and 12 week scan are both booked in for 19th March. Great, because we won't have to wait long now but, from my calculations, I'll only be around 10+5 weeks at that point. Surely it's too early for a 12 week scan? Is it likely they'll need to ask me back in again afterwards?
