Males or Females

Alright I have to for sure females the ones posted I am unsure about. How long until they pollinate my females?? Dont want that to happen. They have like little balls but unsure if it is to early or not, Help please and sorry I could not get better pics any advice on how to get better pics or is it the camera?

anyone have some advice????

Those are just calyxes, which the pistils come out of. They are swollen because they are gonna spit some hairs out, just be patient and if you don't see hairs coming out within 3 days then it could be a male. But i'm 99% sure its just calyxes.

All my plants have these so it is just what happens before a male or female shows? I have read were people can tell by the shape? So if no sign of hairs in 3-4 days it could be male.
