If I haven't had my period in one month and I haven't had any sex, what's wrong with me?

If you have recently lost a significant amount of weight, or have increased your exercising a lot, these may be a few causes, but I would talk to mom/guardian and go see the doctor if it doesn't come

I really wouldn't worry to much about it if I were you.  Sometimes that just happens.  You get lucky and have light periods.  \n\nIt could be because you are dieting and have lost a lot of weight, because changes to the body like that can cause more changes with our monthlies.  Don't worry to much and if you are worried go to the doctor and get checked out but I believe it is just a change in the body.

Because you haven't had sex....

Diet, exercise and stress could all be factors.  If you know, for sure that you are not pregnant then I wouldn't worry about it too much.  But, if another month goes by and still no sign of it, I'd call the doctor right away.

Depending on how irregular you are...if it's the type thing where you bleed alot alot of the time...please do go see your GYN.  I have recently gone through the same thing, only bleeding for months at a time.  I found out something was wrong with me.  I'm not saying there is with you but it's best to know and get treated for it.  Either way, it's still good to go because then you will know regardless.  Dr.'s sometimes prescribe birth control to regulate women also.  Which is a wonderful thing. Trust me :) lol

how long has it been?  any chance of being pregnant?  It could  just be that you have dysfunctional bleeding.  Some women go months at a time without having one and are not pregnant.  I had a cheerleader friend in highschool who went 6-9 months without having a period because she was SO active.  Soemtimes it could be another health issue.  I would suggest checking with your doctor.

Is there a chance you could be pregnant? Or it could be early signs of menapause. If you have been excercising and loosing weight, under alot of stress. These are just shots in the dark. Ideas to think about.

You may be having a kind of hormonal disbalance...Have a checkup done by a gyn or an endocrinologist.\n\nOnce the problem is detected and solved, I don't think you will have troubles to have children

Your hormone levels should be checked.  See your doctor who can correct the problem.

if you are not having sex and you can totally rule that out...(pregnancy)\nit could be stress or change in diet ,  excessive working out\nor it actually be something going on with your hormones

Some medications, stress, and other things can mess up your cycle. You could be iron deficient and have a low blood count.

Not having a period for 3 months is not something to stress yourself out about. .. Stress is the leading cause of female problems. Lack of activity is also a cause. Weight gain or loss can also be another problem. Illnesses can also as well... Doctor's say that woman should at least have 3-4 periods a year. If we don't have at least that. We are doubling our risk for Ovarian Cancer. Periods are shedding our cervix lining.. without the period our lining continues to grow .. running the risk of problems.Talk to your gyno or family doctor. They can check to see if there is other problems contributing to irregular periods. They will check for Endemetreouises. and Poly cystic Ovaries. and any other possible problems. Good luck and let me know how your doing.

could be a number of things go get checked out by your family doctor..if you've had unprotected sex could be your pregnant or something as simple as an ear infection which is accompanied by nausea and dizzines.

If your doctor says there is nothing wrong, perhaps there isn't.  You could see an ob/gyn, or just be grateful for the delay, it's no pic-nic.  Some people have been even older than you.  A lot of it can be your diet and weight...especially if you are very thin.\nYou know though, if my doc said I was fine, I'd be ecstatic.  If all is well, no need to be in a hurry for a lifetime of monthly cramps and irritability.

Not likely.  The most common causes of missing a period are stress, too much exercise/dieting, and being pregnant.\n\nAre you smoking quite a bit extra because you're stressed out?  Maybe the one thing is obstructing the other.
