What Causes The Menstrual Cycle To Change Dates

What Causes The Menstrual Cycle To Change Dates Every Month?

The typical menstrual cycle lasts 25-30 days, however, it may last as little as 21 days or as much as 35 days depending on the individual. Month to month, the number of days in your cycle may change. It’s normal to bleed for 2 to 7 days after getting your period.  If you have regular menstruation, your period is generally around the same number of days apart and will last about the same number of days each month. As a result, you might have a normal period that arrives at a different time each month, for instance, if you have a 22-day cycle, your period may arrive towards the end of one month but in the middle of the next.

As you get older, your cycles may vary in numerous ways. Periods are generally heavier when you’re younger (in your teens) and lighter as you become older (in your 20s and 30s). This is very normal. Menstrual periods greater than 38 days are normal for a few years following your first period. Variation is normal among every type of person, especially when it comes to periods.

To begin with, it may take some time for your body to adjust to the new routine. They may not always last the same number of days or occur at the same time throughout the first few months or even years of having a period. You may even choose to skip a few months. As you become older, your periods and cycles will most likely become more regular. Some people experience irregular periods throughout their lives, whether they are unexpected in terms of when they will occur or how long they will continue.

Why Did My Cycle Change From 28 To 31 Days?

A lack of regular ovulation results in longer cycles. The decrease of progesterone during a regular cycle is what causes bleeding. Progesterone is never produced if a follicle does not develop and ovulate, and the uterine lining continues to thicken in response to estrogen. You’re noticing larger shifts in your cycle. They are generally just temporary, lasting only one or two cycles. These can arise for a variety of causes. The regular ups and downs of your reproductive hormones, as well as the bodily changes these ups and downs, create menstrual periods. They cause the ovaries to produce follicles, the egg to be released (ovulation), and the uterine lining to develop and shed (the period). It’s typical to have a period that lasts between 28 and 31 days. The length of a woman’s menstrual cycle varies, but on average, she has a period every 28 days. It’s usual to have cycles that are longer or shorter than this, ranging from 28 to 31 days.

Sudden Change In Menstrual Cycle Length?

Menopause can also cause disruptions in your regular periods. However, if your periods suddenly become considerably shorter, consult your doctor. Your periods may be longer than normal due to the same causes that produce excessive bleeding. As, Hormone imbalances, polyps, and fibroids, are examples of these. Moreover, you may notice modifications from time to time. Your cycle duration is determined by your hormones, which might change as a result of variables like dietary, exercising, stress, extreme tiredness, working night shifts, or using an emergency contraceptive tablet (the morning-after pill)

You may feel irregularity, missing, or late period for a multiplicity of factors, ranging from stress to more serious medical issues.

  • Medications

Some drugs, such as antiepileptics and antipsychotics, can induce irregular periods. Consult a doctor for intake of such medicines.

  • Eating disorders  

You may have irregular or missing periods if you have an eating problem like anorexia or bulimia. This is due to a lack of hormones produced and circulated by your body to regulate your menstrual cycle. Diet intake must not be taken for granted.

  • Hyperprolactinemia 

Hyperprolactinemia is a condition in which a woman’s blood has too much prolactin, a protein hormone that causes irregular periods.

  • Unchecked diabetes 

If you have uncontrolled diabetes, the interplay of your blood sugar levels and hormones might interrupt your menstrual cycle, resulting in an uneven period.

  • Polycystic ovary syndrome 

PCOS, or polycystic ovarian syndrome, is characterized by an imbalance of sex hormones, which can cause disturbance in the menstruation cycle.

  • Premature ovarian failure

According to the National Institutes of Health, the ovaries of women with POF quit functioning before they reach the age of 40. Some women with this disease, however, continue to experience periods regularly.

  • Stress 

Stress hormones can interfere with menstruation, and long-term stress might cause your period to be delayed or missed completely. The body needs proper relaxation to not miss periods.

  • Menopause

It may also take some time for your period to become regular when you first start menstruation. Up to eight years before menopause, your menstruation may become irregular.

Why Does My Period Date Change Every Month?

You’re noticing larger shifts in your cycle. They’re usually just transitory, lasting one or two cycles. These can occur as a result of 

  • Undiagnosed miscarriage, 
  • Lack of calories,
  • Excessive stress

If you don’t ovulate at all during one cycle, for instance, the next one may be longer and have a lighter period. The next cycle and period may also differ. In most cases, abnormalities in the menstrual cycle are just temporary. However, irregular cycles might persist for a long time. These are cycles that frequently deviate from “normal” ranges (or the majority of cycles in the past 6 months). Long-term abnormalities might occur as a result of activities like working night shifts or engaging in high-intensity exercise, as well as serious illnesses like polycystic ovary syndrome.

Don’t prolong and consult a doctor as soon as possible. Many people suffer from undetected medical problems that interfere with their menstrual cycle. For instance, Endometriosis is a frequent (and underdiagnosed) cause of uncomfortable menstruation.

Does The Period’s Date Change Every Month?


Nope. For every individual the menstruation cycle is different. It varies from person to person if it changes from month to month. Anything that disrupts your reproductive hormone balance can alter the duration of your cycle, as well as your symptoms and the length and intensity of your period.

Moreover, hormones in the menstrual cycle function similarly to those in a relay race. As the cycle progresses, one hormone frequently prompts the next, which in turn triggers the next, causing the cycle to cycle through its many phases. The rate and timing of the cycle will alter whether you have more or less particular hormones. Things can slow down or halt entirely if one hormone fails to “pass the baton.” It’s a delicate and crucial balancing act.

Furthermore, if you are experiencing  any of the following symptoms, every month or for a long time  it may be time to talk to your doctor:

  • For the past 90 days, you haven’t had a period.
  • Your periods are horrible
  • Your menstrual cycle becomes extremely heavy.
  • Your menstruation has started to become erratic.
  • Your menstruation is more than a week long.
  • You have menstruation every 35 days or fewer.
  • You have your period more frequently than every 21 days.
