make sure you have the temps correct in the tank
only one third on one side wants to be with heat mat and a thermostat and thermometre, so u can monitor temps
have a hide in warm side
a hide in cool side
and plenty of hiding places, like old toilet rolls, or branches and decor
mine stays all day in her hide in the warm side and at night, she becomes active when its dark, and moves into the cooler side,
i would suggest, wait one week from her previous feed, then put her in small tub, and have both pinkies together in the tub, if she eats first one, and not the second, jus put the small tub, sealed (withholes of course) someone dark and warm for half hour or so, and check, usually will be gone as they are calm, in the dark etc, and if not, then just leave it until her next feed
but dont over worry yourself, the wait for their growth is worth it over the many years she is alive
