Private scan

Are these worth it? With all my other babes I had the anatomy scan at 18 weeks, but my ob has recently changed it's standards... Meaning I can't have an anatomy scan until 20 weeks. I realize this is not uncommon, but I'm so accustomed to 18 weeks that I don't want to wait the extra time!! I'm 13w1d now.

A private scan around here is roughly 100 dollars, which I'm like no way I'm paying money when I will eventually get a scan... But I'm so impatient. Can anyone convince me one way or the other?!

Hubby is on board with whatever, so he's no help lol
