I'm still not sure what you're worried about. If you would, please answer these questions.
After about 5 weeks from the time you planted your seeds, did you have any male plants? Males are the ones with the flowers that open and drop the pollen, a fine yellow powder.
If you did have males, did you remove them or leave them in with the females?
Did you have a female plant that produced male flowers?
Are you seeing seeds on your plants now, or just calyxes? Squeeze one and see if it is hard or soft.
How old are your plants now?
