11 week 5 day ultrasound. Boy or girl ?

Jamia

So I went to my ob on Monday for an ultrasound and our little baby was jumping and flipping already. We took the nipts test but those results won’t be back until next week. Baby heartbeat has been 180 since 6 weeks. And it was 175 Monday. Any guesses on if it’s a boy or girl. I say a girl but any advice would help :)
