Cold?

The other day I went on break after work and mid-way through eating I forgot I didn’t wash my hands so I panicked. The next two days I had sore throat and bad cough and stuffy/runny nose. I crawl on all fours at work in a grocery store. Is it possible that I could have caught a cold or something from the floor? I know it sounds stupid but my other option was pregnancy cause pollen season is gone and it’s hot af outside right now. I also had a nose bleed.
