I took unwanted 72 on 1st of this month, my normal mense cycle is of 28 days and 20th should be my periods date. But from 10th of this month my periods has been started but the flow is very slow, like hardly half of my pad is getting wet and its been 5th day I am bleeding whereas normally my periods end up on 3rd or 4th day. Please suggest something because usually when i use to take pills, i faced 2 times a month kind off periods but this is the first time it happens to me.
