My menses has exceeded 10 days!
And normally I used to have menses only for 7 days,
So can u please tell me that wait shd I do 2 stop it?

You shouldn't be taking anything to stop it until you have an idea what is causing it. You need to be examined and tested. 10 days isn't really long enough yet, but make the appointment to see a doctor, and you can postpone it if your menses stops in the next few days.
