Not conclusive of anything. Women can fluctuate with their weight within a matter of weeks. It's not like those pictures show a weight gain of over 40 pounds or something. That looks like to be maybe 10-15 pound weight gain at the most. That could be due to her retaining more water weight or eating poorly for a week or so.
Until I see something in her video that references something from late last year or early this year, I am going to assume that any "new" content is actually something she shot within the first 3-4 month of having shot first scene.
