None of your pictures show any male flowers at all.........no "pollen sacks" as you call them, those things are female pre flower calyxes, not male flowers.
Male flowers look like footballs and grow at the end of a little stem.
If you are keen, go to week 7 in my diary "cannabis conundrums" and there are pictures of both male and female preflowers as well as some hermie flowers and these pictures might help you to identify what is going on with your plants in the future.
At this stage, you have nothing to be worried about..........no maleness in any of your pictures.
