Is my condition considered postpartum bleeding (nifas) that exempts me from prayer, or must I make up the prayers I missed during the bleeding, especially since I was unaware of the obligation to pray during that period?

If a woman miscarries and no human features are discernible in the fetus, then the blood discharged is considered dysfunctional blood (dam fasad) and does not prohibit prayer or fasting. However, if human features are discernible, then it is nifas (postnatal bleeding) blood. The minimum period for human features to become discernible is 81 days. So, if the fetus is six weeks old (40 days), the blood is not nifas. But if it is 81 days old or more, and no signs of formation have appeared, then the blood is not nifas. However, if you are not certain about the formation of the fetus after it has exceeded 80 days, the blood is considered nifas. Consequently, nifas prohibits prayer, whereas dysfunctional blood does not prohibit it unless it coincides with the time of menstruation.
