confusing gender

Dena
So yesterday I decided to get a selective ultrasound at 16 weeks cause I couldn't spare the agony of waiting to find out the gender any further.
The tech was very friendly and she knew that I was hoping fora girl since I have two boys but I really don't care. 
The baby wouldn't cooperate and had legs tightly stretched out and crossed at ankles. 
After a couple manuveur tricks baby relaxed a little and she said sorry mother I've been seeing this pointing out at me about six times though his cord is in between his legs I'm positive this isn't the cord. 
We got some great shots and videos even 3D/4d action  of baby practing eating even on his hands and placenta 
Though this is the only gender shot she was able to get. 
What do you guys think ? 
I have a doctors appt on 3/29 I will be 19weeks 
And anatomy scan 4/24 where I'll be 23 , so I think I want to wait to confirm at this appts 
I'm happy either way I'm just ready to go shopping for my baby love !!!
