Irregular menstruation


Hello Doctor: My menstrual cycle is very irregular, and now I cannot have my period without medication.
Recently, I visited a gynecologist who prescribed a 21-day regimen of menstrual regulation medication (once a day).
However, I started experiencing abnormal bleeding (about 10 days into the treatment) that is dark brown in color and has some mucus-like discharge.
Is this normal? Should I stop the medication or schedule a follow-up appointment?

Dr. Cao Guotao reply Obstetrics and Gynecology


Hello, the doctor should prescribe contraceptive pills to regulate your menstrual cycle.
The medication should not be stopped.
If there is still bleeding, it is recommended to return to the obstetrics and gynecology department for further evaluation.
Wishing you good health.

More Info


Irregular menstrual cycles can be a source of concern for many women, and it’s important to understand the underlying causes and when to seek medical advice. Based on your description, it seems that you have been experiencing significant menstrual irregularities, which prompted you to consult a gynecologist. The prescription of a 21-day regimen of hormonal medication indicates that your doctor is attempting to regulate your menstrual cycle. However, the emergence of abnormal bleeding, particularly dark brown discharge with mucus, raises some important considerations.

Firstly, it is not uncommon for women on hormonal medications to experience breakthrough bleeding or spotting, especially in the initial stages of treatment. This can occur as your body adjusts to the hormones. The dark brown color of the discharge typically indicates older blood, which may not be a cause for alarm. However, the presence of mucus can suggest that your body is still undergoing changes in its hormonal balance.

That said, there are several factors to consider regarding your situation:
1. Timing of the Medication: Since you mentioned that you are nearing the end of your 21-day course of medication, it is essential to complete the course as prescribed unless advised otherwise by your doctor. Stopping the medication prematurely can lead to further irregularities.

2. Monitoring Symptoms: Keep track of your symptoms. If the abnormal bleeding persists, increases in volume, or is accompanied by severe pain, fever, or other concerning symptoms, it is crucial to seek medical attention promptly. These could be signs of complications such as an infection or an adverse reaction to the medication.

3. Follow-Up Appointment: It is advisable to schedule a follow-up appointment with your gynecologist, especially since you are experiencing irregular bleeding. Your doctor may want to perform an examination or additional tests, such as an ultrasound or blood tests, to rule out any underlying conditions such as polyps, fibroids, or hormonal imbalances.

4. Potential Causes of Irregular Cycles: Irregular menstrual cycles can be caused by a variety of factors, including hormonal imbalances, stress, significant weight changes, polycystic ovary syndrome (PCOS), thyroid disorders, and more. Understanding the underlying cause is essential for effective treatment.

5. Lifestyle Factors: Consider lifestyle factors that may be affecting your menstrual cycle. Stress management, maintaining a healthy diet, regular exercise, and adequate sleep can all contribute to hormonal balance and overall reproductive health.

In summary, while some irregular bleeding can be a normal response to hormonal treatment, it is essential to remain vigilant and proactive about your health. Completing your medication as prescribed, monitoring your symptoms, and maintaining open communication with your healthcare provider are key steps in managing your menstrual health. If you have any doubts or if your symptoms worsen, do not hesitate to reach out to your doctor for further evaluation and guidance. Your health and well-being are paramount, and timely medical advice can help address any concerns you may have.
