so I've been given a high risk of downs, based on a 4.3mm NT and i guess my bloods anyway the downs itself doesn't bother me and as such me and my OH have opted not to have invasive tests only harmony to confirm, we dont want a miscarrige risk if were not terminating.. my worry is what if its something else? ive read lots of positive outcomes but wondering if anyone else had these odds and came out ok thank you
