That's a tough call Frog man...How long have you been breeding her? The 1st pic does look like ovulation but the 2nd pic looks more like building...You haven't felt any follicles in her at all?...I know for me it's a little harder to feel eggs (once they do ovulate) than follicles...Once follicles are 30 - 35 mm - There pretty hard not to be able to feel - Their like golf balls...If I were in your shoes - I'd keep pairing her up and see if your males still breed her...If she still wraps the water bowl on the cool end I'd say still building - If she makes her way to the heat and stays in that "perfect curl" - She's cooked...Sorry I couldn't be of more help -
