Anybody else have to wait until around the 20 week Mark to find out gender??

I had an appointment today at 17w2d and was hoping to find out the gender. .... but the doc said next appt! :-( he said wait 3 or 4 more weeks...they didn't have anything available around 3 weeks so I have to wait until Feb 11th!! That's one month from today! Uh! Im dying to know, dying to shop dying to start the nursery!!

Feels like most mamas on here already know. I was never offered any blood tests to find out and I'm just sticking with what my insurance will cover for ultrasounds. I had two already.
