I'm on the same boat as you, and I hope my message can help others who are in the same situation.
What I think is that there is nothing you, or me can do to speed up the process, we simply have to wait and see, there is no point in stressing about it, life is too short to worry for more than one year whether or not you'll be moving to the US, imagine if you don't get it, and then you realize you stressed yourself for one year for nothing?
Besides, there is almost 5 months left, the process is not over to lose hope, not even close.
