Well, it could mean a number of things.  A menstruation cycle is individual.  Every woman’s cycle is linked to her own body.  There is no right or wrong way to menstruate.  Some women have quick painless periods lasting three days or less.  Other women have extremely painful periods that can last five to sometimes eleven days. 

So the cycle of a woman’s body is very individualized to them.  Most believe that heredity can play a part in predicting what type of menstrual cycle a women will have.  It is sometime true, but sometimes not.  The most readily believed deciding factor is the individual’s body’s hormones.

Most females are going to have between approximately eleven to thirteen periods a year.

But it is possible that a female can be different.  Factors affecting that individual will definitely play a key part in their own individual cycle pattern.  These can be health.  Health can affect normal menstrual cycles.  Something as simple as lack of proper vitamins in woman’s diet can cause issues with menstruation.  For instance, if women are experiencing period pains but no period, not receiving enough vitamin A, B, C, folic acid or even calcium could be the issue.  Diet, stress, emotional and physical stress can play a factor in irregular periods.

Possible Reasons

• If this is the first year of menstruation, then, it could be just a matter of the woman’s body adjusting and becoming regular.   It can take, sometimes, several years for a woman’s hormones to adjust so that they have normal periods.

• If a woman more mature, then it could be as simple as getting ready to go into menopause.  It is perfectly natural to be irregular when a woman is approaching menopause.

• Could be they are pregnant.  This is the most common cause of not having a period.  There are a number of ways that a woman can diagnose pregnancy.  They can use one of the over-the-counter pregnancy 1′ or urine or blood 1′ at their doctors.

• It can be caused by a weight change.  Either an excessive weight loss or gain has been known to be responsible for irregular periods, as have eating disorders.

• If a woman has period pains but no period it can be cause by a number of other life-factors also such as:  emotional stress, illness, travel, excessive physical activity, illegal drug use.  

If a woman can not attribute any of these possible reasons to period pains but no period, then they may wish to visit their doctor.  Other issues such as problems with pelvic organs may need to be checked out.
