2 vessel cord

Just found out yesterday at my 20 week scan that my rainbow baby girl has a two vessel umbilical cord, they are referring me to a maternal fetal medicine specialist. They also couldn’t get good views of her heart of back in her spine, side looked great she said but they couldn’t see the back side of it. I’m so anxious and nervous as they gave me all the possible things that could potentially happen. Anyone ever experience this? She’s also measuring on the smaller side which they said is common with this condition. I’ve had very complicated pregnancies with both my other children and I was just hoping this one could be a little less stressful. Their worried more about preterm delivery as both my girls were early and it’s common with this condition to have a preterm delivery. So now I’m more worried about that as well. I can’t wait to see the specialist and clear up my nerves hopefully 🙏🏼🙏🏼🙏🏼
