Pregnancy worry

So I have been on Birth Control (the pill) for about almost two weeks and 2 days ago my boyfriend and I had sex and he wore a condom, but we didn't realize the condom broke until AFTER he came. So yes, he came inside me. I'm trying to avoid pregnancy. But I'm on the pill? I'm new to this as well and I'm nervous about what happened. Anyone know my possible chance of being pregnant?
