A couple weeks ago, my female looked big and I swore she must have already built follicles or ovulated already. I paired her then as well. But now, the last 1/3 of her looks thin and totally normal again. So I have no idea what is going on here, or if my female is a dud? I bought her as a proven female, but the price was VERY good, so now I'm wondering whether I got duped LOL.
eta: for some background, I've been pairing her and she has been locking about every 3~4 weeks since November 2016
