I am taking primolut n 3 x a day for 10days, that was prescribed by my doctor since i am experiencing heavy bleeding for almost two weeks, my mestruation stopped but there are some spotting still, it just happened that today was my 5th day of taking the medication and suddenly i bleed again, though it's not that heavy but i though that my bleeding is over, and i am also experiencing abdominal cramps is it normal?
