When does a woman pray and fast after childbirth, and is it true that she starts praying and fasting after ten days?

A woman in postpartum bleeding (nifas) is obligated to pray and fast once the bleeding stops and dries, even if it's only one day after childbirth. However, if the postpartum bleeding does not cease, she is not permitted to pray or fast until forty days have passed, which is the maximum duration for nifas.
