Expert Q & A Answers About urine STD test

Could I have an STD even though my Pap smear was normal?

I am sexually active and have been with more than one partner. Four months ago, I had a Pap smear and it came back normal. However, today I got a sports physical and my urine came back with bacteria. Since my last Pap smear, I have been with just one person and I know he hasn’t been with anyone else. Could I have an STD even though my Pap smear was normal? Do Pap smears detect STDs? I have not had any symptoms or problems.
