If this was her first mating with any male, she could be looking for a place to lay her eggs. Sometimes the first clutch can be laid quicker than normal because you may have bred them too far along in her egg-formation and most of the eggs will be infertile...so she wants to dump them to get on with the production of fertile ones.
All egglaying females, IMHO should have a container of sand/soil in their cages to begin digging in when they are ready to lay eggs. Not having a place to lay the eggs can lead to eggbinding.
Also...don't let her see you watching her while she is digging once she starts digging. Its okay for her to see you when/if she is back up in the branches. She may dig several test holes before she is satisfied with where she is digging or she may spend several days digging the same hole. Once she has laid the eggs (her bum will be down in the hole and her head pointing out while she is laying the eggs) let her cover them completely and go back up in the branches before you dig them up. If its her first clutch, it could be partly fertile and partly infertile...size and whiteness of the eggs will tell.
Have you got a container and vermiculite ready for the eggs when they are laid? A place to incubate them where the temperature is right?
You said..."the other issue worrying me is she refused to eat today"...both the pacing/roaming around the cage and the refusal to eat can be signs of impending egglaying.
You said..."also i have heard/seen that many gravid females close to laying show obvious bulges ect. from the eggs but i cannot see that on her so i was wondering if this is something that all females show"...if this was her first mating and the eggs are infertile, then she shouldn't be to the point of being bulgy if you have not been over-feeding her.
Good luck with her!
