Ovulation?

So i took a look at my female and noticed she is pretty fat and she is about 400 grams heavier than when she locked up the first time. Is this an ovulation?

Based on the pictures I've seen, and my own females, it doesn't look like it. Maybe just building. It'll look like they swallowed a football, lol. When you see it, they'll be no doubt in your mind.

Some females ovulate more dramatically than others. Im not sure if i would call that full on ovulation but you could have caught the begining or end of ovy. Her position looks promising.

This is my girl at the peak of ovy, not HUGE..but still very noticable.

I would say the beginning or the end of the OV.
If you get a picture of her more straight should be able to tell.
