Do females stop glowing or lose some of their glow just before eggs are layed???

One of my females has been in glow since at least the first week of Jan. Im like 90% sure she had ovy about Feb 17th. After "ovy", she shed and she has been on the heat since. After the post ovy shed her normal color returned for..about two or three days and her glow came back after that. Shes been on the heat for a while now and she has been tighly coiled, usually with her tail on the outside of the coil. Over the past few days, maybe about a week, ive noticed here n there her tail has been draped over her body while coiled with her vent in the middle of the tight coil as if shes getting in position to lay. Since yesterday afternoon ive noticed again shes not glowing as intense as before.

What do you guys think? Also, ive been misting her tub at least twice a day to keep humidity up.
