How Long Untill She Gives Birth?

[rrfreak]

I want to know how long do i have until she gives birth. I'm almost posotive she's pregnant, I just want to know how long until she gives birth. She is very silver around the belly and her gravid spot is growing larger and larger and is larger than usual, can you help me?
These are her pics, Sorry for the blurryness

Pregnant, two weeks to go, maybe as little as one week because I can't really judge shape from thos e pics, only size.
