I am not a pro but that is a tough one to call. To be safe I would.....
(1) make sure your incubator is ready and running.
(2) keep the male in with her. Now is a good time to put the male in you want eggs from the most.(just in case she is still building)
(3) If she starts going into shed with in the next 10-14 days it is pretty safe to assume she is gravid.

Good luck with those eggs.

Each year we see ball pythons doing different things. This year I had a female swell up for a week or so. Then ovualted and went down then ovualted the next night again. Two huge Ovs. I had heard of it in boas but not ball pythons. She is due to lay the end of the month.
