Recently this month I've been facing menstruation for about more than 20 days now.I won't say it's heavy flow.I am also not facing any sort of stomach pain.3days ago it stopped but today again I found light bleeding . On the very onset of this month's periods,I wasn't very careful as always.I walked and get up from chair etc at haste.
Also 2-3years back,I was having an issue wherein I was not having periods for about two months.Doctor diagnosed that there was a small cyst as I was not into good exercise and Water (even now I am not into it). Treatment was done successfully that time.After that for 2 years I don't remember having any issue regarding periods.
Nowadays,I am sitting for long hours on a chair ; preparing for a exam to be held in May.
Can anyone mention the cause?
