Question about pink eye (bacterial)

Apparently I have a viral upper respiratory infection that escalated over the weekend to a case of bacterial pink eye. I’m on Gentamicin eye drops, which I’ve been taking over 24 hours, but less than 48. I am no longer having any symptoms. (Yes, I will be finishing the eye drops.) Can anyone tell me if I’m still contagious? I have a very severe case of Obsessive-Compulsive Disorder and am freaking out about spreading this.

Also, I’m slightly confused how I could have gotten BACTERIAL pink eye from a VIRAL infection. The pink eye was definitely bacterial, so I’m wondering if the viral has been misdiagnosed…?
