The menstrual cycle occurs in all females from the onset to puberty (average age 11 or 12 years) to the menopause in middle age (average age between 45-55). The lining of the uterus is shed via vaginal bleeding when a girl or woman has not conceived a pregnancy.

The menstrual period lasts between two days and seven days, usually occurring once every 28 days, although anything from once every 24 days to once every 35 days is considered normal.

If you are having a period more than once every 24 days, it is considered an irregular cycle.

Having a period once every two weeks, or twice a month is abnormal and you should see your doctor because you may become anemic if you are having very frequent periods. They are sometimes a sign of infection or other medical problem that would need treatment.

Reasons for a period every two weeks could be:

• Dramatic weight loss or gain -- This changes the hormones in the body and these are responsible for directing when the period will start.

• Excessive exercise -- This too disrupts hormones.

• Stress -- Exams, family argument, financial worries, divorce, even a holiday can cause a temporary change in your menstrual cycle.

• Illness and/or medications -- Some medications can affect your cycle. Talk to your doctor about altering or stopping your medication if you think this is happening.

• Uterine problems such as polyps, cysts, fibroids or tumors (either benign or cancerous).

• Sexually transmitted infections -- These can cause bleeding in between periods which can be mistaken for a period.

• Thyroid problems -- Thyroid disease could cause a thickening of the uterine lining, resulting in more bleeding than normal.

• Reactions to contraceptive methods -- Sometimes the pill, depo provera injections or the copper-only IUD can result in a change in your cycle.

~ The pill and IUD can make you bleed in between periods, known as "breakthrough bleeding" and this may be mistaken for a period.

~ The IUD can also make your periods heavier.

~ The depo-provera injection can make your cycle irregular, however, it often stops your period altogether instead of making it more frequent.

Hello Anonymous,

Generally, extreme weight loss, and 4 kg is not extreme, causes a late or missed period.

How long have you been menstruating? Have your cycles been regular up until now?

If this pattern continues, speak with a parent. You may need to be evaluated by a physician for a possible hormonal imbalance.

Regards,
Maryann

My periods are always normal however last month it came on time and lasted the normal time but on D14 I started bleeding again not a lot but it was very light and it lasted for 4days......my question is if I am TTC and D14 is the day I was suppose to ovulate and my period came how do I begin to track my cycle again? Also could this be a sign of pregnancy?

Hello Anonymous,

Since you are trying to conceive, you need to consult your gynecologist about this second menstrual bleeding.

Did you have intercourse any time after your last period ended?

If the bleeding on day 14 was very light and ended within 4 days, this could be implantation bleeding.

Talk with your doctor. I would wait and see if your next period starts on time. If not, take a pregnancy test.

Hello Anonymous,

Usually, high levels of stress cause a delay in the start of a period. Please read the article and my reply to the post below.

Any abnormal or irregular menstrual cycle needs to be evaluated by a gynecologist.
