Confused about ultrasound appt

Anon

My 20th week appt is in early January, however I just found out this morning that I needed to make a separate appt for the gender ultrasound. So then I booked another appt that same week but to a different hospital. But I'm completely confused why the doctor that I've been seeing won't be giving me the gender reveal. That's disappointing because I really liked her. I'll be seeing my doctor that Monday and then go see another doctor on Thursday for the gender ultrasound. This is weird to me. FTM mom.

Anyone else in a similar situation?
