HELP Egg bound????

Hi, I am new to gecko breeding, I've been breeding snakes for years and never had this problem till now..

I had 5 Female leos that were gravid, 3 laid there eggs fine about 2 weeks back, I started to think one of the other two was going to lay because she started tearing throught the different nesting boxes for like a week straight.. And then this morning i found her dad in her cage,, NOw i have one gravid female left that is absolutely huge in compariso to the others.. She seems to also be haveing trouble.. is there any way to help save this female..
o, these females were sold to me as proven breeders so should be able to lay fine..

thanks
