Help?? Opinions please??

So I had my ultrasound a few weeks ago (21 weeks). The dr had told me we were having a boy. Looking at the ultrasound pics I’m kind of conflicted and think this is a girl. I already have a girl and a boy. I wasn’t more so leaning to either gender just happy to have another baby coming. I want to know your opinions to see what you ladies think. I’m selling all of my baby girl clothes as this is our last child and hubby thinks it’s cluttering the house lol so if it turns out they were wrong idk. First pic I can maybe see something but second pic idk?? Help??
