Have a look at my diary "cannabis conundrums" and in week 7 you will find pictures of both male and female primordia (pre-flowers) and this may help you to identify what happens when your plant expresses its sex.
Next time you post pictures, just one clear and most importantly, close up, picture under normal light will help people give answers much more easily.
Even if there were preflowers, it would be almost impossible to see them in your pictures that you posted today.
It does not appear to be anything growing at the nodes just yet to be able to say for sure what is going on with this plant.
Be aware though, bag seeds are nearly always the result of plants that have "hermied" during late flower, meaning this trait for going "hermie" will be passed on to the seeds from these plants. So even if your plant does become female, it will have dominant genetics for also growing male flowers/stamens/"bananas" during flowering. There are pictures too of "hermie" female flowers with male stamens/bananas, so these pictures could come in handy if this happens to your plant and this way you will also know what to be looking out for.
Hope this helps,..........
