I've got different dates according to ultrasound and to my last period, and that's so confusing!
Did anyone have similar situation?
My last period was 14th Aug, which means I'm at week 9 now, but I had an US on 5th of Oct and they saw it's only 5 weeks 6 days that time, so 7 weeks 3 days today, which is 1,5 weeks behind the "last period" timing.
I've booked an NT scan, and they told me I have to do it according to the US dates, not period, so they booked me on Nov 15th, but I'm still worrying about it - because of that difference with the period calculations, can it turn up I'm too late for the NT scan?
Or US calculations are more reliable than last period ones?
