Folicles or Ovulation ? albino x 3 males

[Ozone]

Kinda looks like it to me. When was the last time she shed her skin?

i don't remember. i think more than 1 month before. is the 1st time i saw her too swollen from the day that i start breeding her.
yesterday i put the albino male on the cage without any copulation success. today i put the pastel who is better breeder than albino. i will see tomorrow.
when the female is on follicular development must be breed during this time to fertilize the ova?
