Huge Calyx No pollination

I was looking over my plant and i noticed a huge calyx biggest ive ever seen i dont think its polinated because you can still see the pistils and i have no males. I dont think the plant hermied and dropped pollen because there's no pollen on the leaves whatsoever and wind pollination is unlikely because i checked all the buds and only this one was that big, wouldn't more calyxs be pollinated if it was polinated through the wind.
Here are pics
