Still can't tell gender.

Ashley
I'm so frustrated and disappointed. Last night I had my 16 week appt and ultrasound with my OB.  She tried for 15 minutes and baby wouldn't cooperate. We caught a few glimpses but nothing clear enough to determine the gender!
My SO and I were thinking of going for a 3D ultrasound next week. Has anyone had any luck with those?
I'm desperately trying to make this baby seem real and I feel like knowing the gender will help a lot.
