Chances a boy after four confirmed "girl" ultrasounds...?

This is a bit silly but all the questioning from strangers (due to how I am carrying and such) and just in general has my husband worried. We are 32 weeks pregnant, we have had four ultrasound techs say "girl"...from 16 weeks to 30 weeks. Including a 3D ultrasound...three lines seen. But baby has had her legs crossed most of the time, except for the 3D. With our first, a boy it was VERY clear he was a boy. This pregnancy has also been extremely different, with heart burn, and morning sickness. What are the chances really that baby could come out packing? We don't care either way, but he will be wearing pink for a bit.....
