Recent research shows that experiencing shortened intervals between periods is one of the most common symptoms of irregular periods in early menopause.
Irregular periods are often one of the first signs that a woman is going through menopause. Irregular periods signal that estrogen and progesterone levels are beginning to decline, as the ovaries prepare to stop producing these hormones completely.
Though the exact symptoms of irregular periods vary depending on a woman's unique cycle, most women will experience irregular periods for three to ten years before periods stop completely. In fact, only 10% of women reach menopause without any irregular periods.
Read on to learn more about irregular periods and their symptoms, how fertility may be affected, and special cases of these.
Definition of Irregular Periods
In order to define irregular periods, it is helpful to first understand what is considered normal. While every woman is different, normal periods are typically described as having an interval of 25 to 31 days from period start to period start, with bleeding lasting approximately five days. The average amount of blood loss during a normal period is two to eight tablespoons.
While this is a “textbook” definition of normal periods, some women may experience menstruation differently. Thus, irregular periods might be characterized by symptoms that are unusual for them.
Irregular periods, then, are alterations in a woman's typical menstrual cycle that persist for several months. Irregular periods are those characterized by abnormal bleeding and/or unusual cycle lengths. Continue reading to learn more about the specific symptoms of irregular periods.
Symptoms of Irregular Periods
Symptoms of irregular periods may vary depending on the woman, her hormonal patterns, and her menstrual history. Nonetheless, the following characteristics of irregular periods are common:
Did You Know?
See a doctor if bleeding lasts more than seven days or cycles are less than 21, or more than 35 days long.
Common Symptoms of Irregular Periods
Unusual frequency (irregular cycles)
Abnormal bleeding duration.
Changes in flow and clotting.
Infrequent / too frequent periods (oligomenorrhea / polymenorrhea). Periods appearing more often than every two weeks or less than every six weeks are irregular.
Missed Periods (amenorrhea). Missing a period completely is common during menopause. In fact, some women will go months without a period, only to have them begin again.
Painful cramping (dysmenorrhea). While some women experience mild cramping just before or during regular periods, heavy cramping may occur with irregular periods.
Abnormal duration of bleeding. Menstrual bleeding that lasts longer than a week (menorrhagia) or only a day or two (hypomenorrhea). Some women may also experience spotting during the middle of a menstrual cycle.
Changes in blood flow. Irregular periods are often marked by unusually heavy or light blood flow.
Blood clots. While seeing clots in your menstrual blood is often normal (these clots are actually uterine tissues sloughed off with every menses), women with irregular periods during menopause might notice a change in blood clots.
Women who have questions about the symptoms of irregular periods during menopause should not hesitate to speak with their physician. Read on to learn more about how fertility is affected during irregular periods.
Fertility and Irregular Periods
Did You Know?
Menopause is said to occur after a woman has not had her period for one year.
Many women wonder about their fertility when they begin to experience irregular periods. It is important to remember that pregnancy can occur anytime before menopause, even if a woman's period is irregular. It is not uncommon during perimenopause to go months without a period, only to have it return. During this time, it is still possible to become pregnant.
Anovulation is when a woman's ovaries do not release an egg during a menstrual cycle, which occurs often with irregular periods during menopause. It is common for perimenopausal woman to bleed but not ovulate.
Experts recommend that women wishing to avoid pregnancy use a reliable form of birth control during perimenopause until it is certain that menopause has occurred. Read on to learn about special cases of irregular periods during menopause.
Did You Know?
A doctor can perform a blood test to determine if a woman's hormones are officially at menopausal levels.
In some cases of irregular periods it can be difficult to determine whether hormones have reached a menopausal level. For example, taking cyclical hormone therapy, having a hysterectomy, and postmenopausal bleeding are all special cases of irregular periods that merit some additional explanation.
Use of cyclical hormones. If a woman is on a form of birth control or hormone replacement therapy (HRT) during which estrogen is taken on most days and progestin during the last days of her menstrual cycle, she may still have a period, since the latter hormone causes the uterine lining to shed, but she may no longer be fertile.
Incomplete hysterectomy. If a woman has had her uterus removed, but not her ovaries, she is considered “surgically menopausal”, but she may not be hormonally menopausal (since the ovaries are responsible for producing reproductive hormones).
Postmenopausal bleeding. Any bleeding after menopause in women who are not taking HRT should be discussed with a qualified healthcare provider, as this can indicate a more serious health condition.

Many women remain unaware of the fact that irregular periods are a symptom of menopause, and the fact that they can still get pregnant even if their periods are very far apart. Knowing the relationship between menopause and periods and understanding the difference between the stages of menopause is useful information for women.
During perimenopause, estrogen and progesterone levels fluctuate as the body reduces its hormone production in preparation for menopause. The menstrual cycle is largely influenced by hormonal activity, so perimenopausal fluctuations are can have a number of effects on the regularity, duration, and heaviness of your periods.
