Advice?

Cristina
So I got my requisition form for my first ultrasound next week (SO excited!) but my work doesn't know that I'm pregnant yet because I wanted to wait until this ultrasound to make sure everything is looking okay Ect. Anyways, I know my supervisor and she will more than likely won't give me the time off next week for just a doctors appointment she will say I need to give them 2 weeks notice. What would you guys do? 
Thank you in advance!
