Is there any chance of my being pregnant?

No birth control method outside of abstinence is 100% effective. Failure can be ascribed both to the method and to improper use.

But if you are bleeding, you're not pregnant, and outcourse' is much less likely to result in pregnancy than intercourse.

Know that you are taking a small risk that you could get pregnant or STD every time you engage in such intimate contact. Are you willing to take that risk, or would it be better to abstain? Only you know the answer to that question.
