Period Question?

I used to have a regular period and then it started being messed up all the time. But last year i had a period for like 2 months and then it stopped for about 3 months and then I had one that lasted for 4 months...and then I had a normal one for 3 months. And now its doing the same thing. What could be the reason for this.Period Question?
Have you had an abnormal amount of stress lately? Or any major changes in your diet? Any new medications or be taken off any old medications? Sometimes these "outside" factors can affect your menstrual cycle and cause it to become irregular.
You may want to go get checked by your gynecologist because it could be a sign of a much more serious problem, such as ovarian cancer. A little abnormal isn't that disconcerting, but majorly abnormal like yours seem to be is something worth going to the doctor over.

When you get your period for the first time, it's usually not gonna be a "normal" thing. You might get it every month.. You might get it once every 3 months or something.. It just changes sometimes..& If you're older, maybe your body is just going through some changes..
Are you on any Pills?
