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.

Hi, I'm a 48 year old woman and have on occasions gotten my period twice a month for the last couple of years. Considering my age, do you think this could be the onset of menopause?

Hi Anonymous,

Fluctuations in estrogen levels are an early sign of perimenopause. Your menstrual cycles may lengthen or shorten, and you may begin having menstrual cycles in which you do not ovulate.

Women start perimenopause at different ages. You may notice signs of progression toward menopause, such as menstrual irregularity, sometime in your 40s. But some women notice changes as early as their mid-30s.

Anonymous, I would be concerned if you have two periods every month. This could lead to iron deficiency anemia and should be discussed with your gynecologist.

Regards,
Maryann

Hey, my period was always normal from the age of 12 to 14. Starting either in 9th or 10th grade, my periods gradually came earlier and earlier. At some point I realized I had been gettinG my periods every 17 days, twice a month. I've been like this for about 5 years now. I know it has to do with a hormonal imbalance because ever since my period became irregular, I've had terrible hormonal acne that just won't go away. I'm afraid of going to a gyno because I've never been to one because I'm not sexually active. I don't want a doctor looking at my crotch and I'm afraid of needles for blood tests. I thought about taking birth control to regulate my period but my mother won't let me because she wants me to figure out what's wrong with me before I take anything. What should I do?

Hello Anonymous,

I agree with your mother. You need to know the exact cause for this unusual menstrual cycle pattern before any treatment can be prescribed.

I can appreciate your concerns. The first pelvic exam can be stressful to the patient. But, if you choose the right gynecologist, someone who makes you feel at ease, it won't be so bad.

Trust me , needles used to draw blood are so fine, and with a skilled phlebotomist, you won't feel anything beyond the first pinch.

Regards,
Maryann

Thanks for the reply. I think I can handle the blood test, but are you saying that the pelvic exam will definitely happen or is there a chance I might not need one?

Hello Anonymous,

Generally, a pelvic exam is part of the initial appointment. You could always ask when you schedule the appointment.

Hello Anonymous,

Your daughter needs to report this to her gynecologist.

Did she have irregular menstrual cycles before starting the injection?
