I think pic two is actually her at some point of ovulation. If I read it right that was about 10 days ago? She is now going into shed or recently shed. That would put about two weeks between your build pic and shed which is right on target for being gravid. If that is all correct mark your calender for her to lay 30 days from her shed.

After ovulation they will go back down to size and like Justin said it is very hard to feel anything at that time. You should notice her getting bigger again over a wide area in a couple of weeks.

If I misread your post and am wrong, break it down a little better for us, but I would say gravid.
