so you just got her recently, right? sometimes it takes a while for them to settle down and eat regularly. especially if you had her in a cage with a male larger than her--they get intimidated real easy and it can cause them not to eat...and it's good that you have moved her to her own cage but that can also stress her out because she has to get used to another new home. also, make sure she can't see the male in his cage, as that can equally scare her.
my suggestion: leave her in her new cage--alone--and let her get used to it. don't handle her her anything. give her a bowl of calcium with some mealworms always in it for when she gets hungry...and offer her a cricket every day, and if she eats it, feed her some more until she stops.
if she is healthy and fat with a big fat tail, and active, and starts eating better within a week or two, then you have nothing to worry about. if she is skinny and with a skinny tail...sluggish and won't eat and has runny poop then she is sick, and your male might be infected.
good luck, and i hope i helped,
