They actually found the 2 vessel thing when I was having a level 2 ultrasound and according to the tech and the Dr., everything looks good with the bladder (had urine in it), kidneys (although early to tell about everything I guess), heart, brain, spine and digestive system (there was fluid in the stomach, so the baby is swallowing ok).
I guess I'm trying to feel reassured, but I was alone at the Dr appt and was so overwhelmed (and crying a bit) that I couldn't think of coherent questions to ask (like "could problems show up later or are the good US results pretty positive?" etc....)
My Dr, (who is a high risk specialist) seemed very reassuring and calm about it. I wish I could be.
Thanks for the responses and that link...I hadn't seen it.
