Irregular Menstrual Cycles: Causes and Solutions

Menstrual cycle is very irregular?

My first menstruation occurred around the age of 12 or 13, and since then, at 26 years old, my menstrual cycle has been very irregular.
Sometimes it takes a long time for my period to come (three to four months, or even six months), while at other times, it lasts for more than a month (with very little flow each day, but continuing for many days).
Occasionally, I experience heavy bleeding with a lot of blood clots, with the blood color ranging from dark to bright red; at other times, the flow is very light, possibly only one or two cc in a day, or just spotting, with the blood usually being dark or blackish.
Sometimes, I even notice semi-dry blood clots or streaks.

I have consulted many gynecologists and undergone numerous tests; the pelvic ultrasound showed everything normal except for a slight retroversion of the uterus; blood tests for hormones and other parameters were all normal; vaginal examinations were normal; and I even had a Pap smear, which also returned normal results.
I have annual health check-ups, and the results have consistently been normal.
I once took birth control pills to regulate my cycle on the advice of a doctor, but I discontinued them after one or two months due to side effects.
Currently, when my period is delayed for several months, I have to go to the hospital for an injection to induce menstruation.

Although my menstrual cycle is very irregular, I have noticed that my body still experiences hormonal changes each month, such as menstrual acne, bloating, fatigue, irritability, and even menstrual cramps and lower back pain.
These symptoms can vary in severity, sometimes mild and sometimes severe, occurring in a cyclical manner like in other individuals, but without the actual menstrual flow.
What could be the underlying issue? Could you suggest directions for further consultation?

I can only suggest that you cooperate with your physician and not give up halfway.

More Info

Irregular menstrual cycles can be a source of concern for many women, and your experience highlights a complex interplay of factors that can contribute to this issue. Given your detailed description of symptoms and previous medical evaluations, it seems that you have already taken significant steps to understand your condition. Let's explore potential causes and solutions for irregular menstrual cycles.

Possible Causes of Irregular Menstrual Cycles
1. Hormonal Imbalances: Even though your hormone levels were reported as normal, it is essential to consider that hormonal fluctuations can still occur. Conditions like Polycystic Ovary Syndrome (PCOS) can lead to irregular cycles, and sometimes hormone levels can be normal during testing but still fluctuate significantly.

2. Stress and Lifestyle Factors: Stress, whether physical or emotional, can significantly impact menstrual cycles. Factors such as weight changes, exercise habits, and sleep patterns can also play a role. For instance, excessive exercise or significant weight loss can lead to amenorrhea (absence of menstruation).

3. Uterine Conditions: While your ultrasounds have shown normal results, conditions such as fibroids or endometriosis can sometimes be missed on initial imaging. These conditions can cause heavy bleeding, clotting, and irregular cycles.

4. Thyroid Issues: Thyroid dysfunction, particularly hypothyroidism or hyperthyroidism, can lead to irregular menstrual cycles. It might be worth discussing with your healthcare provider whether a more comprehensive thyroid panel could be beneficial.

5. Age and Developmental Factors: Since you began menstruating at a young age, it is possible that your body is still adjusting to the hormonal changes that occur throughout your reproductive years. Irregular cycles are not uncommon in the years following menarche and can persist into the late 20s.

Suggested Directions for Further Evaluation
1. Endocrinology Consultation: Given the complexity of hormonal regulation, consulting with an endocrinologist may provide additional insights. They can evaluate for conditions like PCOS or thyroid dysfunction more thoroughly.

2. Gynecological Evaluation: A second opinion from a gynecologist specializing in menstrual disorders may be beneficial. They might suggest further imaging studies, such as a hysteroscopy, to visualize the uterine cavity directly.

3. Lifestyle Modifications: Consider evaluating your lifestyle for stressors, dietary habits, and exercise routines. Sometimes, simple changes can have a significant impact on menstrual regularity.

4. Alternative Therapies: If hormonal treatments like birth control pills have not worked for you, discussing alternative therapies, such as herbal supplements or acupuncture, might be worth exploring. However, always consult with a healthcare provider before starting any new treatment.

5. Monitoring Symptoms: Keeping a detailed menstrual diary can help track patterns in your cycle, symptoms, and any potential triggers. This information can be invaluable for your healthcare provider in diagnosing and treating your condition.

Conclusion
Irregular menstrual cycles can be frustrating and concerning, but understanding the potential causes and exploring various avenues for treatment can lead to better management of your symptoms. It is essential to continue advocating for your health and seeking the appropriate specialists who can provide the care you need. Remember, while some irregularities can be normal, persistent issues warrant further investigation to ensure there are no underlying health concerns.
