Really a girl?

The first ultrasound was taken at 20 weeks. The second was at 29 weeks. I can definitely see how it's girls at 20 weeks but the 29 weeks one confuses me lol. I've heard 3 ultrasounds where doctor confirmed girl and had him recheck. I've just heard stories of saying girl but baby is a boy. I've got a lot of pink if baby is really boy. Lol what do you think?
