There can be many reasons for that to happen? have you had a baby recently? Are you on BC? are you overweight/underweight? I mean
the only person who can tell you for sure is you doctor. But when I was a teen I went through weird cycles where I would have my period forever, then I would skip it for a few months. The doc wanted to put me on BC and it worked, it put me back into a regular cycle. good luck.
