Pulling out

My boyfriend and I normally pull out.. But the last two times we have had sex he didn't pull out. He never said anything to me. And I'm still on my birth control. I don't know if he is dropping hints he wants a baby or what. How could I bring it up without seeming like I'm accusing him?
