Took a urine test 21 days from unprotected sex and negative. am i not pregnant? also had a negative blood test 15 days from sex.

Not pregnant: Urine pregnancy tests are very accurate and not affected by foods, herbs, common illnesses, sexually transmitted diseases, or medications. A correctly done urine test gives a reliable result 3 weeks after sex (3 weeks after when conception might have happened) or 1 week after missing a period. If done sooner, a positive result is likely real, but a negative result may be due to testing too soon.
