Opting out of my NT scan

Sarah • Wife. Momma to a 2 year old. Praying for our rainbow baby.
My doctor told me it was optional. It sounds like an option for people who want to consider termination if their baby has a chromosome disorder and I am not on that list. I also don't want to give anymore blood. It all seems too excessive. The way i see it is I'm gonna love this baby no matter what. And if there is a problem, can't they just see it on my next ultrasound?
