Reasons for Having a Period Every Two Weeks

why you may be having a period every two weeks

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,

I'm a 14 year old girl whose periods kinda go..crazy.
Once, my period began 2 weeks after the previous one.
And sometimes, my period doesn't come for 2 months or longer.
The weird thing is, even when I take pills for the pain, the pain doesn't go away sometimes.
What can I do to decrease the menstrual pains and make the menstrual cycles more...normal?

Thanks,
Keiko

Im a 14 year old who am having my period for 16 days and still heavy flow, with no signs of stopping. I had my period since 9 and is starting to worry about this. Usually, my period slows down by the 10th day and stops. But this round seems to be going on and on. Please tell me what i should do. Thanks

Hi.. So, I just recently went off my birth control pill about 2 months ago.. I'm trying to have another baby, but my last period came a week and a half early, so I tried again, and my period came a week and a half early again... Does anyone know what this could be caused by or what it might mean???

I have a question. I'm having my period every two weeks, and I heard from a source that that means I have a higher chance of getting pregnant. How true is this statement?

One of the possibilities these articles seem to always fail to mention is endometriosis. Its note common than you think and I suffered for years before being diagnosed. Keep on at the heathcare professionals. It really is not normal.

I have a period every other week which leaves me feeling really tired. My period last for five days each time it comes and its really heavy. I am 22. I have visited my doctors about it, but the pills I received didn't help. Can u please tell me what's wrong with me and if this problem can stop me from having children in the future.
