This varies so much from individual to individual that it would be impossible for someone to give you even a semi accurate general figure as to when she will give birth if she is even gravid to begin with or if we knew exactly when she was bred.
Temp, water offered and food supply can greatly shift this time one way or the other. Now, with all this variables considered, can you really expect someone to be able to give you a reliable figure just from a picture?
I've been breeding scorps for a while and I still get excited and impatient the moment I see embryos, but it could be several months before those embryos turn into babies on her back.
Since Hadrurus have been known require very specific conditions for a successful brood, wouldn't it make more sense to do a bit of research as to how you can be successful with this species rather than stressing her with your camera's flash just so you can have several people wildly blast their opinions as to when she will give birth?
Just some food for thought.
