Anyone told gender earlier than 20 weeks?

I have my next appointment with my obgyn next Friday. I will be 17 weeks and 6 days. I don't know what the doctor will be checking me for, but I'm assuming an ultrasound will be done. Anyone told before twenty weeks? I had an ultrasound around 14 weeks and the technician predicted because I was small in frame. I don't know what she meant. I don't want to get hopeful, but I am just curious. Let me know if you had to wait or got lucky to know sooner (not through blood test).
