Cannot tell gender :(

RedRoses • Pregnant with baby #1 :)
I'm so bummed out :( We had our 20 weeks ultrasound but the sonographer could not tell the gender! She said she cannot see the gender part because of the baby's position.
I have a choice of either asking my doctor for a second Ultrasound, or spending money on a 3D ultrasound that my insurance doesn't cover. Or wait until birth! But that would mess up with my shopping though!
