Abnormal bleeding


Hello, doctor.
I have been taking menstrual regulation medication for the second month now.
My last menstrual period ended on October 24.
Before my last period started, I had some dark discharge, followed by normal bleeding.
However, today, November 1, I noticed some dark discharge again, similar to what I experienced before my last period.
The amount was manageable for the first two days, but on the third day, it increased.
When I wipe with tissue, there is a little bit of blood.
Is this normal? Is this my period? Thank you.

Dr. Cao Guotao reply Obstetrics and Gynecology


Hello, I apologize for not being able to diagnose based on the described symptoms.
It may be due to insufficient dosage of the menstrual regulation medication.
I recommend returning to your original gynecologist for further examination.
Wishing you good health.

More Info


Abnormal bleeding during the menstrual cycle can be a source of confusion and concern for many women. It is essential to understand that while some variations in menstrual bleeding can be normal, others may indicate underlying health issues. In your case, you mentioned experiencing black discharge and bleeding shortly after your last menstrual period, which raises several points worth discussing.

Firstly, it is important to recognize that menstrual cycles can vary significantly from month to month due to various factors, including hormonal fluctuations, stress, lifestyle changes, and even dietary habits. The presence of black discharge can sometimes be attributed to older blood that has taken longer to exit the uterus, which is generally not a cause for concern. However, if this occurs frequently or is accompanied by other symptoms, it may warrant further investigation.

You mentioned that you have been taking medication to regulate your menstrual cycle for two months. Hormonal treatments can sometimes lead to irregular bleeding patterns, especially during the initial months of use as your body adjusts to the new hormone levels. It is not uncommon for women on hormonal contraceptives or other hormonal therapies to experience breakthrough bleeding or spotting, which may appear as brown or black discharge.

However, the fact that you are experiencing an increase in bleeding after a few days of light discharge could indicate a few possibilities. One possibility is that this could be a sign of your menstrual period beginning, especially if you are nearing the expected date of your next period. The transition from light spotting to heavier bleeding can sometimes occur as the menstrual cycle progresses.

Another consideration is the potential for hormonal imbalance. If your body is not responding well to the medication, it may lead to irregularities in your menstrual cycle. Conditions such as polycystic ovary syndrome (PCOS), thyroid disorders, or other hormonal imbalances can also cause abnormal bleeding. If you have not already done so, it would be beneficial to discuss these symptoms with your healthcare provider, who may recommend further evaluation, including blood tests to assess hormone levels.

Additionally, if you notice any concerning symptoms such as severe pain, prolonged bleeding, or any other unusual changes, it is crucial to seek medical attention promptly. These could be signs of conditions such as fibroids, endometriosis, or other gynecological issues that may require treatment.

In summary, while some variations in menstrual bleeding can be normal, it is essential to monitor your symptoms closely. The presence of black discharge and changes in bleeding patterns, especially while on hormonal medication, can be common but should be evaluated by a healthcare professional if they persist or worsen. Keeping a detailed record of your menstrual cycle, including the timing, duration, and characteristics of your bleeding, can be helpful for your doctor in determining the underlying cause and appropriate treatment options. Always prioritize your health and well-being by seeking professional guidance when in doubt.
