Is it normal to miss your period after 33 days?

Women usually have their menstruation once a month, which is about 30 days apart. If it is around 30 days, it is within the normal range for women to have a period. If a woman's menstrual cycle is regular, it means that there is no problem with her body, especially her uterus. Some women find that their menstruation has not come for 33 days, so they want to take medicine to regulate their menstruation. So, is it normal if menstruation has not come for 33 days?

Gynecologists say that a woman's menstrual cycle is generally 28 to 30 days. The length of time varies from person to person, and 20 to 40 days is considered normal. A one-week delay in menstruation is also considered normal, so women don't need to worry.

If you do not have your period for a long time, consider whether you are pregnant. If you are not pregnant, it may be due to medication factors or pathological factors such as the ovaries, uterus, central nervous system, etc. that cause the absence of menstruation. In addition, emotions, lifestyle habits, etc. may also affect menstruation.

Women's menstruation is controlled by endocrine, which can determine whether a woman's body is healthy. The most common cause of menstrual disorders is endocrine disorders. Many women will encounter this problem. Menstrual disorders will cause ovulation, but the schedule is disordered, which has a certain impact on pregnancy. Therefore, when women have menstrual disorders, they should actively seek treatment to avoid causing certain effects on your fertility.

Irregular menstruation poses a serious threat to women's health. Such as menstrual arthritis, menstrual rash, menstrual toothache, menstrual asthma, endometrial displacement, cervicitis, etc. Many women become extremely anxious about their damaged appearance after developing spots and acne on their faces. These spots and acne cannot be solved by cosmetics because they are the reflection of body pathology, and are the external manifestations of irregular menstruation and some cancers, cirrhosis and other diseases.

Therefore, if you want to treat it, you must first know the reason why menstruation is delayed. Generally speaking, if menstruation is delayed by about 3-7 days, women should go to the hospital for examination to rule out the cause.

Why is menstruation delayed? Women with irregular menstruation will definitely be worried. It can be divided into the following five situations:

1. The most joyful reason: pregnancy

For women of childbearing age who have had sexual life, when their menstruation is delayed, they often doubt whether it is menstruation abnormality or they are pregnant. This problem is a very common phenomenon in daily life.

If your menstrual cycle has always been normal, with no signs of delay, and you show some signs of pregnancy, you should test your urine with an early pregnancy test strip on the fifth day after your delayed period (or the fifth day calculated from the start of your period). If the result is positive, you should have a gynecological pelvic examination.

If the cervix changes to purple-blue, the uterus becomes full or enlarged, and there may be accompanying symptoms such as breast tenderness and nausea, pregnancy can be diagnosed. Of course, B-ultrasound can also quickly determine whether you are pregnant.

In addition to pregnancy, delayed menstruation may also be caused by taking this medicine! What kind of medicine can cause delayed menstruation? The following editor will introduce you to this worrying reason in detail.

2. Reasons for concern: Side effects of drugs

Endocrine disorders after long-term use of contraceptives can also cause delayed menstruation. Doctors also found, based on patient feedback, that a new generation of gastric motility drug, metoclopramide, also known as domperidone, may also cause this condition.

2.1. Contraceptive pills: The main ingredients of contraceptive pills are progesterone and estrogen. By taking contraceptive pills, women’s ovulation is inhibited, thereby interfering with the combination of egg and sperm to achieve the purpose of contraception. However, if you take too many birth control pills, the drug ingredients will affect the ovaries' secretion of estrogen, and the endometrium will not grow normally, resulting in a thin endometrium, which will lead to a decrease in menstrual flow or even amenorrhea.

2.2. Diet pills: For example, hormonal diet pills generally contain thyroid hormones, etc. Improper use of diet pills can easily lead to menstrual disorders in women, symptoms of irregular menstruation or amenorrhea, affect normal menstruation, and in severe cases may cause infertility.

2.3. Abortion drugs: Medical abortion generally involves taking receptor-level anti-progesterone drugs such as mifepristone and misoprostol tablets. These drugs will inhibit central dopamine receptors, reduce the amount of hypothalamic releasing factors entering the anterior pituitary, and thus lead to a decrease in the secretion of gonadotropin and corticotropin by the anterior pituitary, causing amenorrhea and delayed ovulation. After the drainage drugs enter the human body, they will damage the endometrium, which requires a period of time to repair. Generally, menstruation will resume about a month after the medical abortion, but menstruation may not come for 40-50 days.

The side effects of medication are not the most obvious and direct reason for delayed menstruation. What else may cause delayed menstruation? Please read on.

3. Obvious reasons: surgery

The surgery will affect menstruation. For example, intrauterine surgery may cause cervical adhesion, resulting in menstrual blood stasis in the uterus, and symptoms of amenorrhea and delayed menstruation.

3.1. Abortion: Abortion generally includes vacuum aspiration and curettage. If the curettage is performed improperly, it may easily damage the cervix or the basement membrane of the endometrium, causing adhesion of the internal os of the cervix or partial adhesion of the uterine wall, thus leading to amenorrhea.

3.2. Ovarian cyst surgery: After ovarian cyst surgery, the uterus and ovaries need some time to recover. Some women resume menstruation one month after the surgery.

Reminder: Pituitary tumors, hypopituitarism, premature ovarian failure, ovarian hypoplasia, etc. may all lead to amenorrhea. What is going on? Let me continue to introduce it to you.

4. Fearful reasons: Pathological factors

4.1. Pituitary factors: The absence of menstruation caused by this condition is also called pituitary amenorrhea. The pituitary gland is located below the brain. Although it is small in size, it shoulders the important task of controlling the endocrine organs of the entire body. If the function of the pituitary gland changes, it will also lead to decreased ovarian function. Common pituitary diseases include tumors and hypopituitarism.

4.2. Central nervous system factors: The central nervous system controls the activities of the pituitary gland and indirectly controls the female ovarian function, including the brain and hypothalamus. When the central nervous system is stimulated, changes in ovarian function can cause amenorrhea. Hypothalamic tumors can also cause amenorrhea.

4.3. Ovarian factor: also known as ovarian amenorrhea. If the ovaries cannot secrete hormones, the endometrium will not change, and there will be no endometrial shedding. Therefore, the endometrium will not change and menstruation will stop naturally. For example, congenital ovarian dysplasia, premature ovarian failure, etc. may lead to no menstruation.

4.4. Uterine factor: also called uterine amenorrhea. If a woman has uterine problems, it may also cause amenorrhea. Common causes include congenital absence of the uterus, uterine hypoplasia, or childhood diseases involving the endometrium, resulting in adhesions or scars. Although the ovaries function well and female characteristics develop normally, there is no menstruation. If menstruation does not occur for a long time after the onset of menstruation, such as endometrial tuberculosis, endometrial schistosomiasis, endometrial suppuration, or when the basal layer of the endometrium is scraped off during curettage, the woman will not be able to respond to ovarian hormones and will develop secondary amenorrhea.

5. Other reasons

For example, factors such as excessive mental stress, high work and life pressure, changes in living habits, irregular work and rest, changes in diet, and changes in the environment may affect endocrine function and may cause menstruation to occur or be delayed.

When the interval between menstrual cycles is more than 35 days, it is called oligomenorrhea, and when menstruation stops for more than 3 menstrual cycles, it is called amenorrhea. The absence of ovulation after amenorrhea can also lead to problems such as osteoporosis and endometrial hyperplasia. Therefore, delayed menstruation must be taken seriously and you should go to the hospital for a comprehensive examination.
