Post-Abortion Bleeding: Irregular Menstrual Cycles and Symptoms - Obstetrics and Gynecology

Post-abortion bleeding


Hello Doctor, I had a medication abortion at a large hospital two years ago due to certain factors, and I had follow-up appointments where the doctor confirmed that everything was cleared out.
Therefore, I did not return for further check-ups.
However, since then, my menstrual cycle has been irregular.
About a week after my period ends, I experience some brown discharge (sometimes black), which appears to have blood streaks mixed with the vaginal discharge.
I also occasionally have mild, unilateral abdominal discomfort, but it doesn't occur every month and lasts for a few days before resolving.
Then, my next period begins.
Could you please tell me what condition this might be and how it should be treated? I am quite worried.
Thank you.

Hello, I apologize for not being able to provide a diagnosis based on what you've described.
Having undergone a medication-induced abortion two years ago should not have an impact.
It is possible that you are experiencing endocrine imbalance.
If you continue to feel unwell, I recommend seeing a gynecologist for an examination.
Wishing you good health.

Post-abortion bleeding and irregular menstrual cycles can be concerning for many women, especially when accompanied by unusual symptoms such as brown discharge, blood-tinged mucus, and abdominal discomfort. Your experience, as described, raises several important considerations regarding your reproductive health following a medical abortion.

Firstly, it is essential to understand that after an abortion, whether medical or surgical, the body undergoes a period of adjustment. This adjustment can manifest as irregular menstrual cycles, which may include variations in cycle length, flow, and the presence of intermenstrual bleeding or spotting. The brown discharge you are experiencing, particularly after your period, is often old blood that has taken longer to exit the uterus. This is typically not a cause for alarm, especially if it is not accompanied by severe pain or heavy bleeding.

However, the presence of blood-tinged mucus and unilateral abdominal discomfort could indicate several possibilities. One common cause of such symptoms is hormonal imbalance. After an abortion, the hormonal levels in your body can take time to stabilize, leading to irregular ovulation and menstrual cycles. This can result in spotting or light bleeding between periods, as well as changes in the consistency and color of vaginal discharge.

Another potential cause for your symptoms could be related to the endometrial lining. If the lining of the uterus has not completely healed or if there are remnants of tissue from the pregnancy, this could lead to ongoing spotting or discharge. In some cases, this may require further evaluation through ultrasound or other imaging studies to ensure that the uterus is clear of any retained products of conception.

Additionally, the unilateral abdominal discomfort you mentioned could be related to ovulation pain (mittelschmerz), which occurs when an ovary releases an egg. This pain is typically mild and can occur on one side of the abdomen, corresponding to the ovary that is ovulating. However, if the pain is severe or persistent, it could indicate other issues such as ovarian cysts or pelvic inflammatory disease (PID), which may require medical attention.

Given your concerns and the persistence of these symptoms, it is advisable to consult with a healthcare provider, preferably a gynecologist. They can perform a thorough evaluation, including a pelvic exam and possibly imaging studies, to rule out any underlying conditions such as fibroids, polyps, or infections that could be contributing to your symptoms.
In terms of treatment, if hormonal imbalance is determined to be the cause, your doctor may recommend hormonal contraceptives to help regulate your menstrual cycle and reduce the occurrence of intermenstrual bleeding. If there are retained products of conception or other structural issues, further intervention may be necessary.

In summary, while some irregularities following an abortion can be normal, persistent or concerning symptoms warrant a thorough evaluation. It is essential to address these issues with a healthcare professional to ensure your reproductive health is managed appropriately and to alleviate any anxiety you may be experiencing. Regular follow-ups and open communication with your healthcare provider can help you navigate these changes and find a suitable treatment plan tailored to your needs.
