Good day all, was wondering if I could use some of your guys experience

This is my first season trying to breed my ball pythons so am still quite new to this all. My one female which i was expecting to lay in the next few days i see is in the blue. A while back she had what i'm sure was her ovulation, the caudal third of her body was about twice its normal size for a day or 2. 15 days later she shed -assumed this was her prelay shed.

Since then she has been lying inverted regularly, gone off her food and been lyingin a tight circle regularly. Her colour has also lightened over the past mth.

Today is day 27 since pre lay shed and I was expecting her to lay soon but see she is in the blue again? Can they shed around the time of lay or have I got something wrong?

She does look big and gravid, could she have resorbed? If she sheds now it means she would have shed twice in just over a month without having eaten anything since 3 weeks before the first of the 2.

I did witness numerous locks since june, and am in south africa so is about the time they lay
