Quoting greysonsmommy:" u can tell them u want to do the ultrasound at 13 weeks its called a nuchal translucency screening its ... [snip!] ... to ask for it. but its def not a yolk sac cause the yolk sac looks like a tiny white dot and its in the same sac as the baby"
Thank you, I already asked doc for that test (I got it with DS at another hospital) but he said he doesn't do that test, only the maternal serum between 16-20 weeks. I am kinda stuck, because I live in northern Michigan, and there aren't many other OB's within 1-2 hrs
So I just have to deal with it. I was perplexed when he told me I wasn't getting a 3 mth u/s though.
