Im having irregular periods. At first i had a heavy flow. Then my flow became irregular and decreased. 4month ago i had heavy flow then next month there were only spots which lasted for 2 days n periods were over. I haven't had my periods since 2+month nw. Its happening constantly. When i take medication my periods come in next week i have heavy flow but once i stop taking those pills (M2 tone) n syrup my periods become irregular again.
