Female with tail suck?

I caught what I thought was tail suck on a female I’ve been pairing since April. She took a small rat a few days ago so she is still on feed. She has been on the cool side since April and is currently on the cool side. She’s a big girl over 3000 grams. Just needed some opinions on if this means she’s ovulating now or could ovulate soon? I see no noticable swell but she looks huge in general.

No… a tail suck is much more obvious usually… and they generally quit eating close to an ovulation as well as start heat seeking.
