Hey girls. This is a menstruation problem. I missed a cycle; can anyone help me figure out why?

Hello everyone.
Well I've had my period for about 8 years now, and it's always been normal. Sometimes my period would be a bit late, like 7 to 10 days late. But it would always show up after some time.

But this month, my period has been 12 days late. I know for sure that I'm NOT pregnant. Is it normal to skip a cycle like this? Or will my period show up after a few more days? Should I expect it to show up in a while? Or will it just not happen this month, and everything will be back to normal by next time?
Has this happened to any other girl out there?

Anyway girls, thanks for your help.

It's true that I have lost some weight over the past couple weeks. But it wasn't anything drastic..and I'm at a healthy weight and I eat well too. So what do I do? Gain the weight back?
And yes, I do exercise everyday, but around the time that I expect my period I stop exercising. I did the same thing this month too, but it didn't matter.

There are milions of girls who havehad this prob before. More often than not it corrects by itself after some time, mostly in three to six cycles. If it does not then you better see an obgyn doctor. There are many reasons why the cycles can go irregular including a malfunctioning thryroid apart from the usual culprits like the hormones. Never try to treat yourself.
