Well my period this month has been longer and heavier than usual. I am usually only on for 4 days and it is heavy for first 2 days but then the last 2 days there is hardly nothing but this month it has lasted for 7 days so far and it has been a lot heavier. I was just wondering if there is a reason for this? I have been told stress, birth control and weight gain can make it longer but I have none of them so is there anything else that can cause this?
