That just happens. Your snake could have gone into a growth spurt in either length or girth, or both. She could have damaged some scales or eye caps which may have triggered the shed. Or she could just be being a snake to confuse things.
All of my adults do the same thing and they are not showing any appreciable growth at all. You would think their sheds would consistently be within a few days of the previous ones. Sometimes they are for a few cycles, then they will throw a 6 month one in there every now and then.
Elvira, my BP once went into the blue just TWO DAYS after a shed. One time she went into the blue and didn’t shed at all!
You can go crazy trying to figure these guys out.
