2 vessel Cord

Sarah
We were told at our anatomy scan today that the umbilical cord only has 2 vessels. They said it can be common but all the other tests, scans, blood work, and ultrasounds came back normal so not to worry. How can I not worry? Especially since they tell you all the possibilities of what could go wrong later in my pregnancy! I'm just trying to keep a positive attitude and I'm greatful that he is still happy and healthy and where he needs to be as of right now!!
