Period or am I pregnant??

So I'm on birth control and I had sex for the first time during this months package. I've had sex 10 times actually this month and every time my boyfriend has pulled out and I take my pills at the same time every day too. I started my first period pill Monday night and had no bleeding. Then my 2nd one last night and started bleeding this morning but it's a super small amount. I usually don't bleed till the 2nd day on my pills anyhow but the bleeding is super small. What do you think?
