Hello, I wonder now I am 11 weeks 4 days according to my LMP. However, I ovulated late this month and it differs 2 weeks. Depending on my ovulation I am 9 weeks 3 days. Next weeks I will have dating scan and combined. Down syndrome test I think can be done 11-14 weeks. So what can happens if I am for example 9 weeks depending on the scan? Will they arrange another scan for combined one?
