2 vessel cord

So I had my anatomy scan just over two weeks ago and at my doc appointment today I was told I have a two vessel cord. There were no other abnormalities found on the scan so I have been told not to worry but we would be travelling to a hospital in the city in about a month to do a level 3 ultrasound. Of course I’m trying not to worry but I can’t help it. Would love to hear any and all of your stories from anyone who has dealt with this. It helps me to have some idea of what to expect. Thank you!
