I have been on birth control for 3 months or less.. I have taken my pill everyday since I have been on it. I have had unprotected sex once since I have been on it. I am sure that he pulled out before he ejectulated. Do I have anything to worry about.

Pulling out is NOT birth control!!!!

Whenever you have sex, protected or not, you always have something to worry about. Even with three forms of because, you can get pregnant. The only way not to worry is to keep your clothes on and not to have sex.

Others will be here soon to give you advice on what to do next.

Is there a reason this was posted in Child and Teen Health forum?

Unprotected sex always puts you at risk for pregnancy and sexually transmitted diseases, so it's not a good idea.
