Since she is still wrapping her bowl, I would assume that she's still building follicles. Keep your eye out for an ovulation soon.

I've been extremely successful with palpating my females while building follicles and then again two weeks or so after ovulation. So far I've been 100% accurate with my projected egg counts for each clutch 11-12 weeks before they're laid. I palpate many times throughout the season to track relative size (while they're still follicles) and I also record how many I feel. I then continue to confirm my count as they become larger and when they become soft (eggs) after ovulation. The count usually fluctates up or down one or two follicles early on, but looking back at my records, for females laying specifically May 18-21 (three females - one last season and two this season), I recorded that I was confident in my follicle count by March 1-4 and all of those counts were correct. The time scale holds true for all of my other clutches too. Also, as Ed said, at a certain point post ovulation you can sometimes distinguish slugs and full-term eggs based on size and softness/hardness. My point is that it is definitely feasible to count follicles/eggs very accurately and predict clutch sizes way before they're laid with patience and practice.
