Not having periods can be caused by pregnancy, stress, or hormonal imbalance.  I suggest your gf see a doctor to find out why she hasn't had periods, and maybe see a counsellor about her emotional trouble.  Be supportive and let her know that you still care about her.

Go get a pregnancy test and find out?\n\nHave you put any weight on?\n\nI had a friend who didn't have a period for 5 months because she didn't eat enough.

There can be alot of reasons a woman misses her period. She could be pregnant. If you are very athletic you may have fewer periods each year. Also if you are malnourished you may not have a period. Those are just a few reasons. You may want to consult your doc on this one.

Stress, pregnancy, hormonal imbalance, weight gain/loss, polyps, and cysts are some factors that can delay a cycle.

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.

There are lots of things that can cause you to miss a period.  Stress, weight gain, weight loss, illness, or  hormonal irregularities.  You should go see your doc, you may need to be given something to jumpstart your period again.  And don't worry!  I once went 8 months without a period and to be honest, it was a GREAT 8 months!

I understand your confusion and frustration.  However, you may be comforted to know that amenorrhea is typically a symptom in and of itself of an underlying condition, but is *rarely* caused by a life-threatening illness. In most instances, symptoms and conditions related to amenorrhea are reversible and treatable.\n\nSecondary amenorrhea happens when a woman who has menstruated previously fails to menstruate for three months. Secondary amenorrhea can be caused by: \n\nPregnancy (the most common cause)\n \nBreastfeeding (lactation) \n\nMenopause, the normal age-related end of menstruation \n\nPremature ovarian failure (menopause before age 40) \n\nHysterectomy (surgical removal of the uterus) \n\nStopping birth control pills \n\nUse of a long-acting progesterone, such as Depo-Provera, for birth control \n\nTumors of the pituitary gland, especially prolactinomas \n\nPolycystic ovary disease, a condition that causes abnormal levels of estrogen, luteinizing hormone and other hormones\n\nEndocrine disorders such as Cushing's syndrome, in which there are very high levels of cortisol, an adrenal hormone, or hyperthyroidism, abnormally high levels of thyroid hormone\n\nEmotional or physical stress \n\nRapid weight loss \n\nObesity \n\nFrequent strenuous exercise \n\nChronic (long-term) illness, such as colitis, kidney failure or cystic fibrosis \n\nChemotherapy for cancer \n\nCysts or tumors in the ovaries \n\nBy way of background, amenorrhea affects 2% to 5% of all women of childbearing age in the United States. Female athletes, especially young women, may be more likely to have amenorrhea. While exercise or physical activity itself does not cause amenorrhea, it is more likely to occur in women who exercise very intensely or who increase the intensity of exercise rapidly. Women who engage in sports associated with lower body weight, such as ballet dancing or gymnastics, are more likely to develop amenorrhea than women in other sports. \n\nThere is a specific algorithm used to diagnose secondary amenorrhea in an otherwise healthy patient. This includes the following steps:\n\nAlgorithm for evaluation of amenorrhea with normal puberty with uterus present - \n\nObtain a pregnancy test. \n\nIf the pregnancy test result is positive, refer the patient to the appropriate specialist. \n\nIf the pregnancy test result is negative, obtain TSH, prolactin, FSH and LH levels. \n\nIf the TSH level is elevated, the diagnosis is hypothyroidism. \n\nIf the prolactin level is elevated, hyperprolactinemia is the diagnosis. Causes include prolactinoma, CNS tumors and medications. \n\nIf the FSH level is low, obtain MRI of the head. If the MRI is abnormal, consider hypothalamic disease, pituitary disease or pituitary tumor. If MRI is normal, proceed with clinical evaluation to exclude chronic disease, anorexia nervosa, marijuana or cocaine use, and social or psychological stresses. \n\nIf FSH is elevated, ovarian failure is the diagnosis. Obtain a karyotype. \n\nIf the karyotype is abnormal, consider pure gonadal dysgenesis, such as Turner syndrome or mosaic or mixed gonadal dysgenesis. \n\nIf the karyotype is normal (46 XX), the cause is ovarian failure. \n\nConsider premature ovarian failure, autoimmune oophoritis, exposure to radiation or chemotherapy, resistant ovary syndrome or multiple endocrine neoplasm (MEN) syndrome. \n\nIf TSH, prolactin, and FSH levels are within reference range, perform a progestin challenge test. \n\nIf withdrawal bleeding occurs, consider anovulation secondary to PCO syndrome. \n\nIf no withdrawal bleed occurs, proceed with estradiol priming followed by a progestin challenge. \n\nIf the challenge does not induce menses, consider Asherman syndrome or outlet obstruction. \n\nIf hirsutism is present, check testosterone, DHEAS, and 17-OH progesterone level. \n\nIf the testosterone and DHEAS levels are within the reference range or moderately elevated, perform a progesterone challenge. \n\nIf withdrawal bleeding occurs, the

Well if you are 100% sure that you are not pregnant then go to your doctor after 5 days.  If you dont get your period in the next 5 days, you could either be pregnant or you might have a problem.  Have you been stressing lately? Stress also makes your period come late.  So relax and wait and if it doesnt come, then head of to your doctor! Good luck!

I'm not Peter O, but it can lead to osteoporosis!  Because...lack of having periods means there is a lack of hormones in the female and "lack of hormones is what causes the (in the case of Osteoporosis) the bone matter to stop replacing dead cells and the bones get weak.

Are you a runner?  If you are very active in sports sometimes you don't get your period.  Remember that getting your period means that your body is capable of carrying a baby.  So if you're underweight or you're too active, your body will think you are not capable of carrying a child so you won't get your period.

Stress is one of the biggest causes of missed or late periods.  Also, sudden weight loss or gain can throw your body off, especially loss.  If you don't get it soon, or if it skips any more months, ask your Dr.  If you are really skinny you might not have enough body fat to menstruate, and that's not a good thing, if you don't menstruate you end up with weakened bones and teeth.  I know it's early to worry about that, you've only missed one period, but I thought I'd tell you just in case it becomes an issue.  Good Luck.

Do you exercise a lot and/or strenuously?  have you been dieting?  If a woman doesn't have a reasonable percentage of body fat, her periods will stop.  You might also have your thyroid checked.  I had the opposite problem -- a period for 72 days, and it turned out I had Thyroid disease.\n\nNo matter what the reason, you should probably have a check-up.  Something's not right...\n\nGood luck!

Well, if you have low body fat content, that is enough for you to have irregular/no periods.  Generally dancers and athletes have this problem.\n\nSometimes a BCP (Birth Control Pill) prescription is enough to fix this problem, as it regulates your hormones.\n\nBut enjoy the no mess!  It's a rarity that women get to go this long without anything.  But always have something on you, just in case -- you never know when it may start up on you again!

It isn't bad. It happens to most of us at least once. The only thing I would be concerned about is pregnancy, but if you haven't had sex, then it should be fine. If you still don't have one in a month or so, you may want to see a doctor just to rule out any problems there. The other thing to look at is if you have lost a lot of weight recently, or started a new workout routine. That can delay or stop your period until your body gets used to it.

boy do I have a story for you!  I once had my period for 23 day straight.  I first went to my normal doctor and she did absolutely nothing.  No tests were run or anything.   I then went to the gyno hoping for an answer.  He preceeded to tell me that it was because I was fat and that the fat cells give off more estrogen and that can prolong your period.  I went home crying still not knowing exactly what to do about the problem.
