Possible: If you had unprotected intercourse there is always a chance of pregnancy. Wait for your next period and then determine if a test is necessary.

Yes: Any time you have unprotected sex it is possible to be pregnant. The blood you observed might not be your period and since you are 2 weeks from your period you are in the prime of your cycle for ovulation and thus becoming pregnant.

Unprotected sex: Any time you have unprotected sex, the possibility of pregnancy arises. Take a pregnancy test if you are not sure.
