Long-term period problems?

I've have regular period since I be ten, so regular that I could predict them three months surrounded by credit. In December 2005/January, 2006 they stopped and haven't come hindmost (except for in the order of 3 days contained by November). I'm 16 presently and starting to obtain nature of worried. I've done profoundly of research on why this could come up, and I've be cart around from one doctor to the other for days gone by 8 months. I lost freight final year, but I'm unquestionably not underweight. Has anyone else experienced this? I really don't know what else to do, and the doctors I hold see (1 common doctor, 1 OBGYN, and 1 young person doctor) are sort of at a loss.
I simply don't gain it. Any planning on the subsequent step?

Period?

There can be copious explanations of why this is scheduled. My best suggestion is ask your doctor if it's possible that you hold PCOS, (there are a great deal of websites for PCOS and enjoy on stripe quizzes see if you fit into that category) if your doctor say yes next you want to find a virtuous Endocrinologist.
Second ask your doctor if the freight loss (if significant) could hold thrown your body into a fit. For some woman losing a colossal amount of solidity will throw their period stale and take them awhile to become regulated.
With you merely human being 16 most doctors are most possible not alarmed and amount your purely still going threw puberty and info it will switch it's self around again. Don't nouns because this may be true. It's tough to determine when a girl is still going threw puberty if it's freshly that or something more. Good luck to you!
