Is it permissible to fast and pray while experiencing colored discharge with blood due to inflammation and not menstruation?

Menstrual blood is that which flows from the bottom of the uterus when a woman reaches the age of religious obligation, according to custom. There are three types of blood from women: menstrual blood, post-natal bleeding (nifas (definition)), and irregular bleeding (istihada). Blood discharged with secretions is not considered menstrual blood unless it is accompanied by the signs of menstruation. It nullifies ablution (wudu'), and one must purify oneself from it and perform ablution for every prayer, similar to the case of a woman experiencing istihada.
