To me, that signifies I need a break. When I first finished the rough draft of my novel (and mind you it took me about a year to write it), I just couldn't do anything with it. The thought of working on it just bored me to tears.
I haven't had writer's block in a long time, because I read a popular writing book (i cannot remember the name!) that said that writer's block was just lazyness. I'd never thought of it that way beforehand, but now I do kind of feel that way. Basically, I started keeping a writing journal, where I jot my thoughts down, and I carry it with me when I'm brainstorming a novel. It really helps a lot.
But back to my initial point. When I first finished my novel, I took a good long break from it for about two months. This cleared my mind a lot. Truthfully, though, I didn't really get my ass back into gear until a few weeks back when I went to a conference. I pitched my novel to two agents that want to see it. I know, really stupid to do when you only have a rough draft. But considering I have to revise it anyway to turn it into a YA novel, it's not a big deal. And I'll be done with it by the end of this week.
So uh, to respond to your post, you should just take a break. Put it out of your mind and don't worry about it. You don't have to wait two months like I did. You can make it just a few weeks or whatever you're comfortable with. It just helps to come back with a fresh mind. Especially if you get to the point where you don't remember what you wrote and you're shocked by how good it is.
