Pic 2 possibly looks like the pistels are starting to come out.
give it some more time and check again in a few days.
You are looking for 2 little white hairs coming out of those little nubs (calyx's)
If you get a cluster of those little nubs forming then those will end up being male. BUT if you get the little white hairs then you have females.
It is still a little too early to tell from the pics.
