You need to get a water test kit. You can get one at a pet store or fish store. The kit should measure ammonia, nitrate, and nitrite levels in your tank. When your tank is cycled, there should be no ammonia or nitrite. Your nitrate levels should be under 40ppm to be safe for your fish.
This usually happens within about 2 weeks in freshwater tanks, given the right things happen.
