Is there an odor to your urine? Do you have back pain? Do you have a fever? Are you going frequently? You will eventually know eventually if you have one. They aren't contagious so you couldn't have "caught" it from your husband. It doesn't cost that much to have your urine dipped. If you have an understanding dr. you could just call him/her and explain you're thinking you might have one and they might send you directly to a lab.
In the meantime, drink a lot of cranberry juice or take cranberry tablets. Hope you're ok!
