I too have a two vessel cord. I'm still worried and I'm 37+4. The worry will not go away until you finally hold your baby and they say everything is ok. I took so many tests it makes my head spin... its not easy. You'll be prescribed to a prenatal cardiologist, they'll offer you genetic mutation blood work, when you get further along you'll have to do fetal heart monitoring (if she's/he isnt moving to much it can last as long as 40mins), and your going to get A LOT of ultrasounds. The anticipation is the worst. Good luck.
