well your ADFs do not have pregnancy. They lay the eggs during mating, the female does not carry fertilized eggs.
You will have to separate the adults from the eggs immediately after mating - they will eat their own eggs and tadpoles.
ADF will often mate with out producing eggs...call it practice if you will haha.
Males will often call several times a week, they are persistent little fellas.
If you do have fertilized eggs, when they hatch they eat live organisms from the water, not filter feed like clawed frogs. For feeding they will need a live daphnia culture.
Also, make sure you have the equipment, time, and space to raise the possibly hundred of tadpoles.
They will need daily water changes and are extremely sensitive to water conditions.
