I have my nuchal translucency US in like half hour and I feel like I'm going to vomit this water up. I have only gotten about sixteen ounces down and I feel like it's coming back up my throat. I am worried about vomiting it all up before I get there. Will they refuse me? How do you moms do this? I've been eating top ramen(no I never normally eat this) because it helps me get more water down plus I'm hoping the broth will add to liquid but my husband really wants this test. What shoul I do?
