I had took an ipill unwanted 72 and is having withdrawal bleeding and cramps. Can i fast during withdrawal bleeding. Dr.s k wadhwa sir, the only islamic ruling on this is - if withdrawal bleeding is similar to periods medically/biologically and if withdrawal blood is similar to period blood in colour, texture, smell and other properties, then no need to fast. So all i need is ur expert opinion on whether the withdrawal bleeding is same as periods medically/biologically
