Cyst on umbilical cord?

Christina • Due May 6th with a little princess💕 single mom😁
So I went in today for my first appointment and sonogram and the doctor said there looks to be like a cyst on the umbilical cord. He also said that it's really early and he can't be for sure. I'm currently measuring 8 weeks 4 days. I have to go back in 5 weeks for another sonogram and he wants me to do genetic testing. I was just curious to see if anyone else has had this in their first trimester and what was the outcome? Thanks in advance!
