Do I have synesthesia?

I'm not sure if I do. I tend to ociate numbers to certain colors. For example the number 3 is pink, the number 5 is an earthy color, the number 10 is just black, the number 69 is always blue to me. And when I think of months in my head it's like a giant cycle. Toward the begining of the year I see cool colors, then around spring it's light colors then I picture a curve as May changes into June. August is never really memorable, just like a brief time in the year. Then by November theres another curve into December which are usually darker colors. I also ociate colors to memories like when I cut my hair really short last year I always see brown. I know this sounds weird but do I have synesthesia?
