When should I start?

Hey y'all. I already posted this on another group, but I want a couple of opinions. So I'm 15, and i just got a prescription for birth control...

And I'm wondering when I should start them. She said I could start them whenever, or I could start them on my next menstrual cycle. I'm wondering what you guys think is better. Also, am I supposed to take these pills while I'm on my period, or not?
