I took a test im almost a month late. So it could be stress, diet change, horomonial imbalance, weather, could be many things, could even be astrology so don't stress just take a nice aroma therapy bath and lay in a dark room with a candle (scented) lit or incense to calm your self...

Major causes of changes in the menstrual cycle are stress and pregnacy. But, if u'v done a pregnancy test and u r sure u are not pregnant...\n The other things that could disrupt ur menstrual cycle are changes in environment, change in weight and eating disorders, Hormonal contraception ,Eating disorders (anorexia, obesity, weight fluctuations, poor nutrition ,Stress ,Systemic illness (DM, hypothyroid,TB) ,STD ,Medications .\n\nThe best thing u could actually do is to see ur OB-GYN!

I find it is lack of sleep or stress.  Maybe both.  It can take a long time to get rid of them or reduce them.  More often than not, one good night sleep does not make up for a week of late nights

Several things can make you late besides the obvious one.\nStress, taking medication (colds, infections,  ect.) New type of birth control.  or ...What we use to call "staking" your BC pills to skip (prolong having a period) Or there could be a number of more serious illnesses. Advise female friend to see her Dr.

How old are you? Irregular periods can be caused by many things including bad eathing habits...anxiety, if you weigh very little you maybe missing your perioud often, when you mean last year... when? i think you should see a doctor asap. Health problems are not a joke. something could be wrong. Also when you say you have not had sex... are you saying that there was no penetration but you played around abit? the sperm is known to survive for upto 72 hours (www.teenwire.com or 6days according to that website). My take... see a gyno immediately... this is important. and there are clinics that you can go to that are not costly. ask your friend to go with you. goodluck

Stress could definitely be the cause, but don't just assume it's the cause in your specific case. If you miss more than one, you should go see your doctor. Other possible causes: poor nutrition, extreme loss/gain of weight, extreme increase in physical activity, drug use (including some medications), or problems with pelvic organs.

It often takes a while for your periods to get back to normal after stopping birth control, particularly if her cycle was irregular before she started taking it. Other causes of missed periods include dieting, poor nutrition, extreme exercise and stress. She should visit her doctor in case there is an underlying cause, but I had a similar situation, with no other symptoms, and nothing was wrong. It is also possible that the pregnancy test result was wrong - sometimes, negative results are inaccurate.

Theoretically you could be pregnant. The symptoms you have don't seem typical to me at all...\n\nSo try to take it easy - and if your period is more than a week late, take a test.

It may be difficult to get pregnant because if you don't have a regular period, you may not be ovulating properly.  One common cause of irregular or no periods is polycystic ovarian syndrome (PCOS).  PCOS is an endocrine system disorder linked to insulin function that causes an overabundance of male hormones.  5-10% of women have it.  Other symptoms of PCOS can include acne, being overweight, thinning hair, male-pattern body hair growth, dark patches of skin (hidradenitis suppurativa), insulin resistance, or infertility caused by lack of ovulation.  However, the most common and noticeable symptom is irregular periods.  I had only 3-4 periods a year when I was diagnosed with it.  Your gynecologist can do blood work to test your hormone levels and see if you may have it.  Fortunately, many women with PCOS can get pregnant with proper treatment.

If you have a late period and a negative pregnancy test, then consider whether or not you’ve recently been sick, gained or lost a significant amount of weight, have been under excessive stress or have taken any new medications. All of these things can affect your menstrual cycle and cause you to have irregular periods. Additionally, certain types of birth control, including the birth control pill, Depo-Provera and Norplant, can cause you to have menstrual cycles disturbances.

You should make an appointment to see a gynecologist to have them perform a thorough exam. Sometimes this irregularity can be caused by hormonal changes.  If you are young this may be the case.  In some instances time or with the aid of birth control pills(if recommended by you physician), hormones can be regulated.  It is also wise to have your doctor do an exam to check for other causes that may be serious, causing the extended length of time of your period.  The sooner you have yourself checked out the better off you will be to corrrecting the problem.

Irregular menstruation can sometimes be caused by hormonal imbalances. It can become a serious condition if it persists, for the loss of blood can cause a variety of other medical problems from leucemia to death in more sever conditions. The good news is that your sister is planning to visit the doctor at the onset of the problem, this will certainly maximize her chance of preventing this from happening in the future. Do remember that if it does happen to be a hormonal imbalance, then it will also take some time in order for the hormonal levels to restore themeselves to their required limitations.

It would be best to talk to your doctor about that. It could be a number of things, but it would be safer for you to speak with a doctor. Don't worry about not getting your period yet, some people are just late bloomers and there shouldn't be anything to worry about.

Some of the common reasons for women to have irregular periods [excluding menapause, pregnancy, miscarrage, birth control etc.] would be a sudden drop or gain in wieght or sudden increase in physical activity.  If none of these apply to you, you may need to contact your doctor.  Hope all is well.  Good Luck!

Your period is probably just being irregular. At 17 your body hasn't completely worked out all of the kinks that come along with periods, and yeah, you'll occasionally be late or skip a month. It could also be related to stress or being sick (if you have been recently). I wouldn't worry about it.\n\nHowever, it wouldn't be a bad idea to go to a gynecologist anyways and get checked out, and maybe put on birth control if irregular periods are a problem.
