hope this is in the right spot.
I went for my NT scan and bloods yesterday and i am a week less pregnant than i though i was (11 weeks instead of 12) so they asked me to come back next week to re-scan me. I had my bloods taken.
My question is.. Will the blood take at 11 weeks still be ok to test? Or do i need to have blood taken on the same day as the scan?
I hope this made sense. I tried to call my midwife today but couldnt get through to her, so any advice would be great.
