I Had Sex For The First Time 2 Days Ago,

I had sex for the first time 2 days ago, he used the pull out method. He didn't ejaculate inside of me but I'm worried sick of I'm pregnant or not. He's told me that he's going to be there for me no matter what happens. The doctor I had talked to told me to get a pregnancy test done next week. I haven't told my parents what happened, I'm too afraid to. By the time I see the guy I had sex with again is on Saturday, is there any birth control I can take by the time it's Saturday or on Sunday that will stop any chances of me getting pregnant?
