14 weeks only see one artery in chord

So I had my first scan yesterday and I’m slightly further along than I expected ( only by a week or so) but they’ve said they can only see one artery so far in the chord.... everything else is measuring up fine and she woman said she’s not worried at all she said she wouldn’t of even told me about it but she had nothing else to report back, she said some babies do only have one chord and are born perfectly fine just at a lower birth weight.... she said we might be able to see it by my next scan as the artery may be too small to see now but she said there’s also a small chance it could be because of chromosome abnormalities but my bloods will determine if I’m at risk before my next scan, so if it comes back a low risk and they still see no second or third artery they aren’t going to worry..... BUT IM WORRIED 😂😬😬 waiting for my bloods is now an anxiety ridden time.

This happened to anyone else and everything turned out fine???
