im having the same problem with my female. i got her from georgia dragons and she looked healthy till i took her to the vet for a check up. the vet told me she had parasites, some rott mouth, and she was under weight. when i contacted georgia dragons they said thats normal for a female who just laid eggs and that they cant do anything about it. i got some weight on her and she started brumating and now i am afraid that she is going to die. anyways to keeo some heat in your cage try covering half of your lid it will help with humidity too.
