Pollen will not kill plants, otherwise plants would be extinct!
Your plant is female, but the flowers in the first 3 photos look like they have been pollinated and have seeds forming, as evidenced by the lack of pistils (white hairs) and the swollen appearance of those calyxes. So, there could be a sneaky male flower or 3 lurking somewhere.
For pictures of what female primordia/pre-flowers, male flowers and hermaphroditic flowers (male and female flowers growing from the same "bract") look like, go to my diary "cannabis conundrums" and in week 7, you will find the pictures as well as some other pictures of weird and wonderful things cannabis plants are capable of doing.
Hope this helps,........
