Vaginal discharge


Hello Doctor: I have had regular menstrual cycles since I was young and have never experienced menstrual cramps.
However, about 2 to 3 years ago, I started having occasional ovulation bleeding (not every month).
Since this year, I have been experiencing abnormal bleeding during non-menstrual periods, sometimes red and sometimes brown, often accompanied by blood streaks or small clots.
There is no foul odor, and the amount is very minimal, just a little bit each day, with variable duration and occurrence, even during non-ovulation periods.
I also noticed that it seems related to exercise; every time I engage in intense abdominal exercises, walk for several hours continuously, or do vigorous jumping, I experience abnormal bleeding the next day.
I would like to ask the doctor what might be causing this issue.
Additionally, I have been dealing with acne for about 7 to 8 years, primarily located on the sides of my chin.
Could this be related? I have not used any medications or topical treatments for acne.

Due to abnormal vaginal bleeding, it is recommended that you consult a nearby obstetrician-gynecologist.
A thorough medical history and gynecological examination by the physician will help in making an accurate diagnosis and determining the appropriate treatment.

Abnormal vaginal bleeding can be a concerning issue for many women, and understanding its causes is essential for effective management and peace of mind. Based on your description, it seems you have been experiencing irregular bleeding that is not associated with your menstrual cycle, which can be distressing. Let's explore the potential causes and considerations regarding your symptoms.

Firstly, it is important to note that abnormal vaginal bleeding can arise from various factors, including hormonal imbalances, structural abnormalities, or even lifestyle factors such as exercise. In your case, you mentioned that the bleeding often occurs after engaging in vigorous physical activity, which could suggest a few possibilities.

1. Hormonal Fluctuations: Hormonal imbalances are a common cause of abnormal bleeding. The menstrual cycle is regulated by a delicate balance of hormones, and any disruption can lead to irregular bleeding. For instance, if you are experiencing ovulation bleeding, it is typically due to a drop in estrogen levels that occurs just after ovulation, leading to a slight shedding of the uterine lining. However, if this bleeding becomes more frequent or is accompanied by other symptoms, it may warrant further investigation.

2. Physical Activity: Engaging in intense physical activity can sometimes lead to changes in your body that might trigger abnormal bleeding. This could be due to increased abdominal pressure or even minor trauma to the vaginal or cervical area during exercise. If you notice a pattern where bleeding consistently follows certain activities, it may be worth discussing with your healthcare provider.

3. Structural Issues: Although you have mentioned that previous examinations have ruled out significant issues, conditions such as polyps, fibroids, or endometrial hyperplasia can cause irregular bleeding. These conditions may not always be detected on initial examinations, so if your symptoms persist, further diagnostic procedures like a pelvic ultrasound or hysteroscopy might be necessary.

4. Infection or Inflammation: While you did not mention any pain or foul odor, it is still possible for infections or inflammatory conditions to cause abnormal bleeding. Conditions such as cervicitis or vaginitis can lead to irregular bleeding, and a thorough examination can help rule these out.

5. Acne and Hormonal Links: Regarding your long-standing issue with acne, particularly localized to the chin area, this could be indicative of hormonal imbalances, such as those seen in polycystic ovary syndrome (PCOS). PCOS can lead to irregular menstrual cycles and abnormal bleeding, as well as acne due to elevated androgen levels. If you suspect a link between your hormonal health and your skin condition, it may be beneficial to discuss this with your healthcare provider.

In conclusion, while occasional irregular bleeding can be normal, especially if it is minor and infrequent, the persistence and pattern of your symptoms suggest that further evaluation may be warranted. Keeping a detailed record of your bleeding patterns, associated activities, and any other symptoms can provide valuable information for your healthcare provider. It is essential to communicate openly with your doctor about your concerns, including your exercise habits and skin issues, as these may provide clues to underlying hormonal or structural issues. Regular check-ups and appropriate diagnostic tests can help ensure that any potential problems are identified and managed effectively.
