Gender predictions early

Anyone have early gender predictions? I’m not even 4 weeks according to the calendar and I keep referring to my baby as a boy and I’m just so positive it’s a boy. I want a girl but I’ll be happy either way :) I’m trying to hold off on finding out the gender until he/she is here. Hopefully I’ll make it! What are your predictions for your little ones? And when did you first start thinking it was that gender?
