16 week sonogram

So we went for an early sono purely for fun and curiosity. I’ve been feeling girl the entire time and then saw the first picture.

The tech said she was pretty certain boy. Then she saw second picture.

She wavered a little but then said she was still thinking boy. So what do you all think? I’ve come to terms that it may not be a girl after being in that mindset the entire pregnancy but after some research online I’m not 100% convinced.
