Possible, but again can't tell with the pics. A possible hermie, pollen carried into the grow on yourself or the wind. Regardless, males don't make seeds, nor do females. A female needs pollen to make seeds. Once seeded, the pistils recede and start to work on the seed production. A better pic, or take a closer look at the calyx. Even opening one will tell you. A light squeeze on a calyx to see if it's getting hard as the seed is forming. As you said, you are nearing the end cycle, so it's more than likely just swelling up with sticky goodness.
