I had my first ultrasound last week at 13 week, and was informed yesterday that the nuchal fold is thicker than they would like. I went in for blood work today, and I am waiting for an appointment for another ultrasound with a high risk doctor. I don't know when my ultrasound will be yet, and was told that it will probably take 2 weeks to get the results for my blood work. I'm not sure as to the exact measurement as the nurse didn't say. She said it may be due to a chromosomal/genetic abnormality (such as those that cause Down's Syndrome) or it may be nothing. I hate not knowing and the wait is driving me crazy, even though I've only known for about a day. I've been nervous eating, which I haven't done in years. I want all the sweets and salty snacks right now. Has anyone else been through something like this?
