Yes. How could you know you didnt "leak". Precum is viable and that means she could get pregnant. Anytime there is penetration especially without a condom she can get pregnant!
Sighhhhh...didn't you listen in health class? You are supposed to use a damn condom! Yes you should be worried because any time you have unprotected sex, even if you didn't "come or leak or anything" there is still a risk of pregnancy. IF she is pregnant you will just have to live with that decision to have unprotected sex for the rest of your life! Was it really worth it?
