I took one yesterday & i was wondering about the green stuff at the bottom, too. I'm assuming it's the powdery stuff that was already in there that just didn't dissolve all the way? Mine almost looks like it settled at the bottom. I think mine is a girl result, as does my dh, but it's so hard to be sure! I think i'm going to email intelligender & see what they say about mine. Who knows, maybe i'll get a free one, lol!
Once i figure out how to put a picture on here, i will post mine. Yours definitely looks like a girl result!
