If the growth looks like a ball sack on top of a stick then male. Female preflowers stay close to the node and are a pear shaped and will send pistols out the tip. From the node region on the right, it looks like it is a pear, so I would say female. Give it a few days to be sure and make sure she throws pistols out. If she doesnt throw the pistols out, then you will see the separation like I was talking about.
