I had previously told my midwife that the first day of my last period was 10/11/10 but my DP pointed out that that cannot be correct because I got my new flat on Monday the 8th but didn't move in until the Wednesday which was the 10th, we couldn't do it that night because I still had my AF but we did the next night because it had gone. My AF only last's 5 days at the most so that means it must of begun on sunday the 6th November. If this is correct which I think it is that means I am actually due 15th August 11 instead of the 20th!! Which makes me 11 weeks and 2 days pregnant! Do you think I should bother switching it or telling my midwife? I'm just worried because she said give it to being 13 weeks before contacting her if I haven't heard from the scan people but if I do that it means technically leaving it until I'm 14 weeks and don't you have to be under 14 weeks to do the nuchal test?
