Menstrual irregularities have been persistent?


I got my first period in the second year of junior high school.
Since then, my menstrual cycle has been very irregular, ranging from two months to three or four months, and even up to six months.
Recently, I experienced some premenstrual symptoms, and the discharge was dark brown, but it disappeared after a few days.
Now, the same situation has occurred again, but my period still hasn't come.
Why is this happening? Please help clarify, thank you!

Generally speaking, irregular menstruation can be explored through brain hormones, ovarian function, and the uterus.
However, given your age, the issues are primarily related to the first two factors.
If academic or life stress is too high, the brain's gonadotropin-releasing hormones may be insufficiently secreted.
A similar situation can occur with rapid weight loss and in individuals with anorexia.
Additionally, being overweight can lead to elevated levels of male hormones, which can prevent ovulation.
If there are accompanying symptoms such as blurred vision or milk secretion, it is necessary to check for potential brain tumors.
If there are also signs of mental fatigue, thyroid function should be evaluated.
Furthermore, the use of psychiatric medications or treatments such as chemotherapy and radiation therapy can also lead to amenorrhea.
Regarding the ovaries, conditions such as ovarian cancer (or cysts) and poor ovulation function are also causes of irregular menstruation, so it is advisable to follow up at a clinic.

Irregular menstrual cycles can be a source of concern for many women, especially when they experience significant variations in timing and symptoms. Based on your description, it seems that you have been experiencing irregular periods since your first menstruation, which can be attributed to several factors. Understanding the causes of irregular periods and potential solutions can help alleviate your concerns.

Firstly, it is important to recognize that menstrual cycles can vary widely among individuals. A typical cycle ranges from 21 to 35 days, and variations within this range are often considered normal. However, when cycles extend beyond this range or are consistently irregular, it may indicate an underlying issue. In your case, experiencing cycles that span from two months to six months can be classified as oligomenorrhea, which is defined as infrequent menstrual periods.

Several factors can contribute to irregular menstrual cycles:
1. Hormonal Imbalances: The menstrual cycle is regulated by a complex interplay of hormones, including estrogen and progesterone. Any disruption in hormone levels can lead to irregularities. Conditions such as polycystic ovary syndrome (PCOS), thyroid disorders, or hyperprolactinemia can cause hormonal imbalances that affect your cycle.

2. Stress and Lifestyle Factors: High levels of stress, significant weight changes, excessive exercise, or poor nutrition can all impact hormonal balance and, consequently, your menstrual cycle. Stress can particularly affect the hypothalamus, which plays a crucial role in regulating the menstrual cycle.

3. Age and Developmental Factors: Since you mentioned that your irregular periods began in your early teens, it is worth noting that menstrual cycles can take several years to regulate after menarche (the first menstrual period). It is common for young women to experience irregular cycles during this time as their bodies adjust to hormonal changes.

4. Underlying Medical Conditions: Conditions such as endometriosis, uterine fibroids, or pelvic inflammatory disease can also lead to irregular bleeding or changes in menstrual patterns. It is essential to rule out these conditions through appropriate medical evaluation.

Regarding the deep brown discharge you mentioned, this can often be a sign of old blood that is taking longer to exit the body. It is not uncommon to experience brown discharge before or after your period, but if it is accompanied by other symptoms or persists for an extended period, it may warrant further investigation.

Given your situation, it is advisable to consult with a healthcare provider who can perform a thorough evaluation, including a physical examination, blood tests to check hormone levels, and possibly imaging studies like an ultrasound. This will help identify any underlying conditions that may be contributing to your irregular cycles.

In terms of management, treatment options will depend on the underlying cause of your irregular periods. If hormonal imbalances are identified, your doctor may recommend hormonal contraceptives to help regulate your cycle. Lifestyle modifications, such as stress management techniques, a balanced diet, and regular exercise, can also be beneficial.

In conclusion, while irregular menstrual cycles can be concerning, they are often manageable with the right approach. It is essential to seek medical advice to understand the specific factors affecting your cycle and to develop a personalized treatment plan. Remember, you are not alone in this, and many women experience similar challenges with their menstrual health.
