Ustadh, at the end of my period I check w/ tissue & it’s always dry. Apart from that, I have dark brown discharge for 3 days, usually after the toilet or lifting sth heavy. Should I judge by the dry tissue or wait until it turns white/yellow?

If your cycle is done and then afterwards brown discharge starts coming out, this is not your period. You can disregard it.
