I'm getting an ultrasound soon

My bestfriend ever (let's call him Max - we've been best friends since preschool even though I'm a girl and he's a guy) is helping me pay for it. He has a job and his parents are kinda rich, I should get a job soon. Anyway he's paying for the ultrasound which is super sweet, and they're not cheap. So soon I'll find out if I'm having a boy or a girl (I'm kinda hoping for a girl even if I won't be keeping it). The appointment is Monday after school.
