First ultrasound. Help please!

Just left our first ultrasound, 7 weeks 2 days, (I had calculated 7 weeks 5 days) heart rate was 160! ❤️

The ultrasound tech was pretty much a jerk though and he only showed us the baby for a split second and boom we were out of there in 4 minutes total.

Can anyone please help me out by guessing which end is the baby's head? He didn't show us anything except for there it is and there's a heartbeat. I would love to know which end is baby's head!

Thank you!
