I wish i knew how to zoom in using firefox. Darned technology.
Anyway, to answer your question:
If there is a little hair popping out of the very tip of that, it's a female. If there isn't, then it either needs more time, or it's a male. I can't really tell from the picture, so i suggest grabbing a magnifying glass and checking it out. I agree with the others though, that say to wait a little longer. Just to be sure and not get your hopes up.
