Can I get an std from urine?

Basically, I am a female. I was wearing a pad. I was kinda sweaty working out, so the adhesive was basically gone. As soon as i dropped my pants to go to the bathroom, the pad fell in the toilet! I didn't have any additional ones with me, so i just kinda placed it back in my pants after drying it off. I was wondering if it was likely that I would get an std from this experience. Thanks in advance!
