im saying hen only one row of peas.
The Feed Store said it's a pullet when we purchased the Ameracauna as a 1 Day old Chick. At 10 weeks old, I'm wondering if we have a rooster on our hands. It's too pretty compared to the other Ameracaunas, We aren't allowed to have roosters in our town so I will be sad to lose this gorgeous bird if it turns out to be a boy!
true ameraucanas are pretty hard to find. And many feed stores get their chicks from hatcheries (who call their EE's ameraucanas...so it is confusing!) 
That looks like a single comb to me.
on second thought yea.... now im thinking its a boy
That's not an Ameraucana, it's an Easter Egger. Ameraucanas have pea combs and don't come in that color. It could be a pullet--hard to tell. At about 10 weeks is when cockerels will begin crowing. Listen for that. Also, look under its back feathers, a little less than halfway up its back from its rump. Do you see thin feathers with slightly different coloring coming in? Those will be saddle feathers. If you don't see any, likely it's a pullet. Or they haven't started developing yet. My 10 and 11 week old cockerels all have the beginnings of saddle feathers so you should see them any time.

It has pretty bluish green feathers on the tail, is that what you mean? Are the Ameraucanas that different than EE's that they'd have different looks in gender presentation?
I've never seen am EE pullets with plumage that color, so I'm going to have to say male.
