I enjoy a quiz going on for my time...
Answers: It has happened to me and my friends profusely. My best friend missed two months of her period, and she's not sexually active, so she wasn't pregnant for sure. And it sometimes doesn't come when you expect it to. Just lurk a little longer and see, and if you still don't see it, see a doctor. Hope I helped!.
there's really no set rota at a young age and mine was close to that too,mine used to skip a month or so and then it would come back but i agree near the first answerer.if it does not regulate then go see a doctor. For some girls, it can rob a year or two to regulate. However, because it has been since December and you are very soon 16, its best to see your gynecologist for a check up.
