Is she in one of those tiny plastic container? If she is, you need to let her out as they are very stressful for the fish. Ideally they should not be used at all, and if one really must be used the female should only be put in one immediately before giving birth. Leaving her in one for days or possibly weeks is not good for her.
The best way to use these traps is to leave the female in the tank to give birth, and have a lot of hiding places for the fry (plants, real or fake) then catch the fry and put them in the trap.
