Help!

So hubby returned home from deployment last week and we had LOTS Of sex but i also started birth control (Pills) last Sunday the same day i started hubby hasn’t pulled out 🤦🏽‍♀️ he doesn’t know I’m on birth control but is there any chance that i will still get pregnant? We had sex like 8 times and half of those times he didn’t pull out 😩😩🤦🏽‍♀️
