This month while I was on my periods, a problem occurred. I usually bleed like any other 19 year old girl should. however in this month I bled for two days. from the third day i stopped bleeding. the napkin was white. right now it is my 5/6th day and i had been bleeding just 2/3 drops since the third day. p.s. I smoke. previously it did not affect me. but i m suspecting probably it's because of smoking.
