Clinical 2 Vessel Umbilical Cord

Nancy • Wife.Mom.Babywearer. 3 boys and 1 girl.
Has anyone dealt with one artery in the umbilical cord close during pregnancy?
I have another scan in 2 weeks, but in the meantime, I've been given very very little info from the OBGYN, and am terrified to google anything.
I was hoping to see if other mamas went through this and how it was for them.
