I have a question about the chance of pregnancy. First off I took all my birth control pills for the whole month with out missing any, and had my period. But on the last day of my last brown pill I had sex and my boyfriend may or may not have got pre in me. He pulled out and a lot of it came out on the bed. But I am worried.

Any time you have sex, pregnancy is possible. There is no form of birth control on the market that's 100%. There are too many women that were using 3 forms of birth control and still because pregnant, some more than once. It happens.

The only way to avoid pregnancy 100% is to avoid sex. So yes, you could be pregnant. That's a possibility any time you have sex, even if you use the pill and a condom, and another form of birth control.

You'll have to wait and see what happens with your next period, and then continue to play the waiting and worry game every time you have sex. But you're having sex, so surely a child wouldn't be a huge shock. You must be ready for that since you're having sex. Right?
