DEPO AT 17

I have so many questions about women who are currently on Depo (birth control shot):

For starters when do you know it’s finally worked?

When having sex if the guy doesn’t pull out can I get pregnant?

Do I have to take an emergency conception pill if I’m on depo?

Is there anything I need to know as a 17 year that I need to be aware of going on this birth control?
