Is anything incumbent upon me even though I did not know of the obligation of prayer after the cessation of postpartum bleeding and before the completion of forty days?

The cessation of blood for a woman in postpartum bleeding (nifas) obligates her to pray and fast, even if she has not completed the full period of nifas, which is forty days according to the majority of scholars. She is also obligated to perform ghusl (ritual bath) and make up all the prayers she missed from the day her nifas bleeding stopped. It is recommended to learn the rulings of purity (tahara) and specifically the rulings concerning blood.
