There are various reasons as to why a female period will come every two weeks. Most women will experience an irregular period at some stage in their life. Menstrual irregularity can happen because of a range of things that will affect the levels of hormones, including illness, stress, pregnancy and diet changes. However, irregular periods that are ongoing, particularly a period which occurs every second week, could be indicating a more serious complication.

Stress has the ability of altering a female’s hormone levels and could interfere with diet and sleep as well, which will further throw your hormones out of sync. This could actually be the main culprit in for causing irregular, more frequent periods.

Exercise and Diet
Exercise and diet alter the amount of calories that feed hormone production and essential body functions. When the production of hormones is altered, menstrual cycles can slow down or speed up, leading to frequent periods.

While menopause will ultimately lead to the absence of a period, it could initially affect your body in different ways, including periods that are more frequent.

Birth Control
Contraception will deliberately alter the hormones in a woman’s body. Birth control will usually cause light bleeding or skipped periods between cycles. It could also sometimes cause a woman to have a period every second week for a little while.

Ovarian Cysts
Ovarian cysts are clumps of fluid which develop on a woman’s ovary. A lot of women will develop cysts, but most of them aren’t an issue and will disappear by themselves. Those that do not flush away naturally with the menstrual cycle could get bigger. A large cyst can cause frequent and abnormal bleeding with pain. This can lead a lot of women in believing that their periods are coming more frequently. Large cysts could cause damage within a woman’s reproductive system and have to be surgically removed.

Inflammatory Bowel Disease
This disease affects the intestine and colon and can cause bleeding, leading a woman to think she is having frequent periods. This disease is treated with an anti inflammatory medication.

This can mean an abundance of things. Firstly of course, this does depend on your age.  If you are an adolescent, between the ages of 11 to 19, irregular periods are very common and can be either a sign of reaching your adolescent peak, or simply that your body is adjusting to the hormonal changes that are occurring in your body. This period of adjustment is perfectly normal and once you have past adolescence your periods are more than like to have become more regular.

Other causes for irregular periods can additionally attributed to disruptions in specific contraception’s, such as the contraceptive pill. If the contraceptive pill is not taken regularly, following the instructions on the packet, then this can cause your period to come at irregular interval. Moreover, it can also be affected by an imbalance to hormone level of oestrogen and progesterone. These hormones are important to regulating the menstrual cycle, and if these hormone levels are disrupted, then you may experience bouts when your period will be arriving at irregular intervals.

Similarly, irregular periods are also common when a woman is nearing her menopausal stage, but again this is natural process like puberty, and it is very common for a woman when she is about to or is going through the menopause to experience these irregularities to her menstrual cycle. To regulate your periods, doctors sometimes advise that you go on the contraceptive pill, though this is less common for women of menopause age. Additionally, specific vitamin supplements can be taken to regulate your system such as vitamin B and Magnesium supplements. However, if you do not fall into any of the above categories, then it may be advised to seek medical advice, as the irregularities could be caused by something else.

This is clearly not a usual occurrence as a period should be normally once every month when the egg that has not been fertilised and womb lining are dispersed from the vagina. Most women have their periods every month as their cycles of menstruation are usually around 28 days.
You can be a few days late in having your period but in this situation your menstrual cycle has been disturbed and this could be down to a number of factors including stress-related illness and tension as well as a particular hormonal imbalance in your system. If for any reason you are experiencing difficulties with your period then it is advisable to consult with your doctor.
If you do decide to take a trip to the doctor, then it is advisable that he runs a series of physical examinations and blood tests to find out what the cause of the problems are. Dont worry, he may only want to take blood tests to find out if you have anything wrong with your blood count.
You could also have an imbalance of the hormone oestrogen in your system which could explain a possible imbalance and the reasons why you may be suffering from irregular periods. It also could be that you are near menopause or reaching puberty. During these tough phases of a woman's life, periods can also become irregular leading to problems. If again you feel you belong to one of these categories then you should also seek medical advice.
If for any other reasons you might feel like you are missing your period or there is no bleeding or discharge that is coming from your vagina whilst on your period this also could be another factor as to why your hormonal balance could be disturbed.

It's not unheard of, but it's not ideal. It could be that you are having breakthrough bleeding when you ovulate, but whatever the cause you need to see your doctor, as bleeding this often is tiring and lets face it a pain in the ****. If you have only recently started having periods, maybe let it be for a couple more months to see if it settles down a bit on its own. But don't put up with it for years!

There are some women who do have periods twice a month but it is not normal. You need to see you GYN for an exam. He most likely will put you on something to help regulate you.
