What do you guys think it is BOY or GIRL

Sarai • Baby girl Due January 2019

These are photos of my 15 week ultrasound. What do you guys think it is boy or girl?

I was told there was a possibility it was a girl but then they said a boy so now I’m 18 weeks and I’m going to wait for my 20 week ultrasound to know for sure. I just want opinions.
