Am I fertile (Male Fertility)?

A while back me and my fiancee were trying to conceive. After two months of trying we broke up, I was wondering if it was me. So I bought a microscope and created a sample I found when I got out more. And ate things that were prepared rather than m produced. More of my guys were moving further but like today I've been drinking a lot of caffeine. And eating fast food, and they seem to be wiggling really fast but not moving. This is how I normally take care of myself, also I heard that your suppose to use something to dilute it I haven't.
