Did anyone not have 1st trimester genetic testing?

Our gc is at an obgyn who does not do the nt scan and doesn't do the bloodwork until week 16. He said he's happy to refer us to another practice that can do it between week 11-13. We need to move quick if we are going to schedule it because we are 11 weeks on Sat. I want to know of anyone has waited until week 16? I just feel like that's far out.
