Give it a couple of swirls in the bucket and re-test in a few days. It may be doing it's work slowly, especially since you didn't rehydrate the notty.
After repitching mine it has been slowly bubbling away. I haven't tested the gravity since then, but I figure I will wait until Sunday to give it a full week.
I made the mistake of dry hopping before checking the gravity the first time. I was going to just dry hop in the primary for 14 days at the end of fermentation. So, I had hops ontop of a stuck fermentation. oops!

So I think I will still add another oz of hops when I transfer in 2 weeks to a secondary. (yeah, I'm really messing this batch up

) This will bring my total hop usage for this batch up to 7 oz! At least I'm keeping good notes so I can reproduce it if this turns out good.
