There is a pre-flower there, see the little ball on the bottom left of the stipule? It could be male or female at this point tho, so just give it a few more weeks.
If its female it'll sprout the tiniest little pistils...I'd say it's make from where on the node the preflower is located but I'd definately wait it out and see cos every strain is slightly different.
I hope it's a female for you tho!
