A girl or too early to tell? help please :)

I had my ultrasound done at 14 weeks and the tech said it was a girl but she seemed so unsure. She kept saying she wanted to get more angles. I tho k she applied the nub theory as well, and I'm not sure what the time frame is for the nub theory. any help or comments? definitely a girl. We're waiting on our OB to call us back so he can order another ultrasound for confirmation but I'm just so anxious lol. anyone else have an ultrasound like this and it was a boy?
