Still waiting for eggs

[little_dragon_]

At first I though i would get eggs the third week into march because my gecko's mated several times the last week of febuary but now it's april 7th. I have increased misting, the day time temp reaches 78/80 with a cool spot as well. She has a couple places to lay eggs. My gecko looks fat . Today I decided to seperate her from her mate and placed her in her orginal tank with another female hoping she will lay. Any advice?
