Finding out gender tomorrow (hopefully)

Had my appointment today do check for down syndrome and what not. Am currently 17 weeks 5 days pregnant. I asked my doctor about the ultrasound and he said he won't schedule me until 20 weeks. I know that's about 2 weeks from now but I can no longer just wait especially since am at the point where I nothing seems to be happening, no nausea, no cravings, not feeling any baby movement etc. So I made an appointment for tomorrow at one of those prenatal imaging centers. My appointment is at 11 so I can't wait for today to be over.
