Is my Phidippus Regius gravid or just fat?

I've noticed her abdomen is the biggest I have ever seen. She has not mated since her last molt but recently reinforced her web and extended it quite a bit.

She could just be getting ready to lay a dud sac. Pretty common in jumpers, but still a fun surprise!

She won't produce a viable sac unless she mated after her last molt.
