2nd to last picture looks like there is something in there.
Last picture looks like she has worked everything out.
That last picture makes me believe she's in good shape.
If you have any doubts an ultra sound or X-Ray or both would be the only way I know to really find out for certain.
You can firmly run your hands down her body kind of palpate to feel what you can feel.
If it feels like there could be hard lumps in there then I guess
you would have to talk to your Vet and come up with a plan.
By the way sorry you got slugs it is such a let down after waiting and anticipating, . . very much of a downer.
Hopefully your fem will go back on food and recover nicely.
My guess is your probably mistook preovulation swelling for an ovulation and pulled the male.
Also what sometimes complicates things is the male will loose interest for no apparent reason.
This is when back up males are so important 
My male Albino lost interest too early this season also and I
believe this will impact the litter he was involved with too. 
As they say next year try again
