I am having my period yet I find myself having the ability to fast. Is it permissible for me to fast during my period?

It is impermissible for menstruating women or those in post natal bleeding to fast. The issue of menstruation and post natal bleeding differs from the fast of the sick and travelers. Breaking the fast on account of sickness and travel is a legal dispensation, while it is obligatory for women in menses and post natal bleeding to refrain from fasting.
