Hopefully my doctor will make this appointment when I find out my gender. I'm going to be 17 weeks can't they find out already? I'm not going to find out but, sadly my dad is incarcerated and I'd like to just show him an envelope saying what I got before they transfer her out of San Antonio since his court date is next week :(
