If her buccal gavity (her throat) is full, she has eggs or fry and her
behaviour is subdued and she stops eating. You can release the fry by
holding her just above the water mouth down, and opening her mouth open
with your other thumb. just dip her head in and out of the water until all
the fry wash out.

  To wait for two weeks and then remove the female at this time would be 
  very dangerious as the female may spit the fry out or she could swallow
  them.  I have never heard of stripping mouthbrooders of there young and 
  would think that this would be near impossable.  In a ideal world you 
  would have a separate tank but this case you have not and I would leave 
  her where she is for now and wait till they are big enough to remove.

Actually, the removal of fry from a mouthbrooder is quite common and has 
been studied 
rather intensively.  The one method that I have seen entails the use of a 
large 
'kitchen baster'.  When you place the female (quickly!) in the baster and 
gently 
squeeze, she releases the fry (i.e. they get squirted out into their new, 
safe tank).
I agree that it could possibly hurt the female, but at least the fry would 
have a 
better chance to live outside of a tank full of hungry adults :)  . In any 
case, it 
always pays off to have an extra tank around for a hospital/nursery.  I 
would say this 
 is especially true if you keep tanks full o' squabbling cichlids.  

Cheers,
pete
