So I had an ultrasound at 11 weeks and the fluid behind the neck was measured at 5.5. I did the blood tests and everything came back normal. I had an ultrasound yesterday at 12 weeks and the fluid is down to 3.5. But still said something could be wrong because it was there at the beginning and it’s still high. They recommended the amniocentesis but I don’t think I want to risk that. Any mommas have a similar situation and everything was completely fine and the baby was completely healthy?
