Soooooooo BC? And just the tip?

So i started taking my birth control pills for about 2 weeks now. And I've been on track and on time every 8:30pm. And i let my bf put it in raw for a couple of thrust and he took it out. And we continue with condom. Should i be okay? Because he never finished. And my BC says that i should be protected after 2 weeks of taking it. I'm sure I'm fine. Just need another opinion... plus so many of my friends have done the pull out method and haven't gotten pregnant. And I literally let him in for 40 seconds. So i should be fine... right?
