Is my king snake gravid??

[Punk Angloid]

I have a 2008 pair of california kingsnakes and decided to try and breed them this season, i cooled them ect and after her first shed after cooling introduced the male, they locked up ect. I introduced them several more times (3-4) then she rejected him and she seems to be puffy and such but im inexperienced and am not sure.

She feels softer/squishier in her lower half than else where on her body.
Shes also been eating w/ ravenous apettite recently.
