Dee, sorry to hear of your worries. My NT scan and bloods put me in a very low risk category. I was pretty happy about that and then at my 18-20 week scan, they found a "small unilateral choroid plexus cyst" that is synonymous with Trisomy 18 - for which I'm in a very low risk category. Apparently they're common and disappear...but, you can't help but be concerned, so I can relate a little. Hope you're feeling a little better today.
