Birth control and him coming inside you

Brandi
I need help! I have been on the birth control pill for 4 years now, and take them religiously. I have never missed a day. My fiancé and I have sex without condoms because of this reason but we still use the pull out method. Last night, he came in me for the first time ever and I did not know what was going on until after. Now I'm worried that we may have taken it too far and put full trust into the bithcontol. Would I be in a high chance of becoming pregnant? Does anyone else take birth control and let him cum inside you?
