Published at 23 September 2024

A delayed menstrual cycle does not always mean pregnancy. It is very common for the menstrual cycle to be irregular, as 14-25% of women of reproductive age suffer from some menstrual problems. Let us learn about other causes of delayed menstruation. (1)(9)

The normal rate of delayed menstruation: When is it considered late?

If the menstrual cycle is late by a day or two, or once every now and then, this is normal, but the menstrual cycle is considered delayed, especially if it happens repeatedly in these cases: (2)(10)

If you are 7 days or more late for its date.
If it has been more than 35 days since your last period.
If your period is usually very regular, and it is more than three days late.

Keep information about your menstrual cycle, either on paper or digitally on dedicated phone applications, including the start and end date, and a list of any other associated symptoms, to track personal health and so that the doctor can provide appropriate care. (3)

Reasons for delayed menstruation

The reasons for delayed menstruation can be summarized as follows:

1-Stress

Severe tension and continuous physical and psychological stress affect the level of hormones regulating the menstrual cycle, and this causes a delay in the menstrual cycle. However, when stress is eliminated or reduced, the body regains its balance, the hormones regulating the menstrual cycle return to normal, and the cycle regains its regularity after a while. (5)

2-The big change in routine

Any major change in your daily routine can temporarily affect your cycle, such as travel, night shifts, changed sleep patterns, or crash diets. (4)(5)

3-Significant weight gain or loss within a short period

A large change in weight in a short period can affect the balance of hormones in the body, and thus lead to a delay in menstruation. (5)

4-Excessive exercises

Excessive or very strenuous exercise can sometimes lead to irregular periods. (2)

5-Near menopause

If you're in your 40s or 50s, a late period may be a sign of approaching menopause. (2)

6-The first years after puberty

The menstrual cycle can be irregular in girls who recently started periods, and this continues during the first years after puberty. (5)

7-Hormonal contraceptives

Starting or stopping contraceptives or using other hormonal contraceptives can affect your menstrual cycle until your body adjusts. (3)

8-Breastfeeding

If you've recently gave birth and are fully breastfeeding, this may stop your menstrual cycle temporarily; Due to increase the prolactin hormone increase, knowing that this hormone may increase in non-breastfeeding women for other reasons in some cases, and it affects the menstrual cycle as well. (1)

9-Some medications and treatments

Some medications and treatments, such as chemotherapy and radiation therapy, can affect the menstrual cycle and delay it. (3)(6)

10-Hormonal disorders

Hormonal changes can be caused by factors such as polycystic ovary syndrome (PCOS) or thyroid problems. (3)

11-Diseases and other health problems

Certain medical conditions such as endometriosis, fibroids, ectopic pregnancy, or ovarian insufficiency can lead to irregular menstrual cycles. (3)

What should I do if my period is late?

If your menstrual period is late, Seek medical attention in the following cases: (8)

If your period is delayed 3 times in a row.
If you have polycystic ovary syndrome symptoms, the most important of which are: acne, weight gain or difficulty losing it, and excess hair on the face or body. (2)

If you are married and your menstrual period is late, take a pregnancy test. You can take a home pregnancy test at least a week after your missed period, because taking the test too early could give a fake negative result even if you are pregnant.
