Hi, I am 25 yrs old. I am having a prolonged period of 14 days as of today. It is not very heavy but just a streak of blood, mostly thin, sometimes thick and sometimes a smal patch of blood. There is no recent ailment I can think of. Is it because of weather condition. I do not feel very weak or seldom any pain. I am just worried about the period I am having for the last 14 days. It never happened to me earlier. Is it normal?
