Are you able to smell any CO2 or other fermentation products in the bucket? If so, you certainly have fermentation. From the sound of it, all is going well.
Next time, make a starter (like the others said) and pitch your yeast at a slightly higher temperature (~85F). Also, if you didn't aereate, do so. All those things will help with any beer, and especially with higher gravity ones.
At what temperature are you fermenting? If you are on the low side, you see slower yeast activity.
