My menstrual sycle this month came 6 days earlier,usually cames noramlly?!

No, that's pretty normal. I wouldn't worry unless this happens more frequently or this change is accompanied by heavy bleeding, fevers and/or extreme pain. Take care.

If it normally comes at the time it is supposed to and this is a first it could be something. Was your cycle any different than it normally is. But it is probably just nothing unless something seemed really unusual about it. and if something was unusual i would suggest seeing the doctor so you can figure it out and not have to worry.

Nope! Nothing to worry about. Periods are not an exact science they can come early, arrive late, be heavier or lighter then normal for no reason.
