Is it obligatory to perform ghusl and pray when pink discharge, not menstrual blood, appears at an unaccustomed time and continues for days then stops?

What a woman sees in terms of discharge outside the time of menstruation, and it does not have the characteristics of menstrual blood, is not considered menstruation. Rather, it is vaginal discharge. Its emission does not necessitate ghusl (ritual bathing), but it does nullify wudu' (ablution). If its emission is continuous, such that it covers the entire prayer time, then the woman must perform wudu' for each prayer after its time has begun.
