Is my emperor scorpion pregnant? is something else wrong with her?

I had 2 emperor scorpions, 1 male, 1 female. They had been in the same enclosure for about 2-3 weeks, then one morning i found my male dead. My female is now very very aggressive and is always at the hot side of the tank, she hasnt went in her hide with in the last 4-5 days. And she never refuses food, lol. But do you think she might be pregnant? Sick? Or something is wrong with her?

What are the tank parameters? Substrate/Temperature/Humidty/etc ?

How long have you been noticing this behavior?

Also, if you could post pictures it would greatly help in determining if your P. Imperator is gravid.
