Why won't my aquarium cycle?

I have a 37 gallon tank with 4 mickey mouse platies. It's been nearly 6 weeks, and the tank refuses to cycle. For the last 3+ weeks, ammonia has been around 2 ppm. Zero for Nitrite and Nitrate. I do partial water changes about once every 10 days. What am I doing wrong?
