Vaginal bleeding


Hello Doctor, I am 155 cm tall and weigh 50 kg.
I was previously diagnosed with polycystic ovary syndrome (PCOS), and I have excessive body hair and frequently experience acne, which appears on my chest and back.
Although my menstrual cycle has been irregular over the past two years, I have been getting my period, usually with a light flow lasting about 8 to 9 days.
Occasionally, I experience heavier bleeding accompanied by menstrual cramps.
Sometimes I have spotting during ovulation, but due to the light menstrual flow, I sometimes cannot distinguish between menstrual bleeding and ovulation bleeding.
On July 7, I had continuous bleeding for about a week, and then I experienced bleeding again around July 25 that lasted until August 5.
After researching online, I became very anxious, fearing it might be cervical cancer, which has led to feelings of depression.
When I visited the doctor, since I have not engaged in sexual intercourse, the doctor only performed an abdominal ultrasound, which suggested that it looked like ovulation bleeding, and my uterus appeared normal.
I was prescribed hemostatic medication, and after taking it for three days, the bleeding stopped before I finished the medication, so I did not continue taking it.
However, on August 19, I experienced bleeding again for about 8 to 9 days, and then on September 7, I started bleeding again, which has continued to the present.
Recently, the bleeding has been light enough that I only need to use a small sanitary pad.
Although the doctor mentioned that the likelihood of cervical changes is low due to my lack of sexual activity, I found many cases online of virgins who discovered they had advanced-stage cancer, which frightens me greatly.
In the past few years, I have occasionally experienced intermenstrual bleeding, but doctors have not been able to find any results (I have not undergone a pelvic exam).
Recently, I have been needing to wear sanitary pads for more than half of the month, which is uncomfortable and concerning.
I am really worried that I might have cancer.
What should I do? P.S.
I suddenly remembered that during the summer vacation two months ago, I often went to sleep around 3 or 4 AM, and I wonder if that has had any impact.
Thank you very much, Doctor, for taking the time to read this.
Wishing you health and safety.

You may consider taking birth control pills to regulate your menstrual cycle; you can consult your obstetrician-gynecologist about this.
Wishing you good health.

Abnormal vaginal bleeding can be a source of significant concern for many women, especially when it occurs outside of the regular menstrual cycle. Your symptoms, including irregular bleeding patterns, prolonged bleeding, and the presence of pain, can indeed be distressing. It’s important to understand the potential causes of these symptoms and the steps you can take to address them.

From your description, it seems that you have been diagnosed with polycystic ovary syndrome (PCOS), which is known to cause irregular menstrual cycles, hormonal imbalances, and symptoms such as excessive hair growth and acne. Women with PCOS often experience abnormal bleeding due to the lack of ovulation, which can lead to the thickening of the uterine lining and subsequent unpredictable shedding. This can manifest as prolonged periods or unexpected bleeding between cycles, sometimes making it difficult to distinguish between menstrual bleeding and ovulation bleeding.

The bleeding you experienced on July 7 and again on July 25, lasting several days, may indeed be related to your PCOS. The fact that your doctor performed an abdominal ultrasound and found your uterus to be normal is reassuring. It suggests that there are no immediate structural issues such as fibroids or polyps, which can also cause abnormal bleeding. The use of hemostatic medications was appropriate, as they can help manage excessive bleeding.

Your concern about cervical cancer is understandable, especially with the information available online. However, it’s important to note that cervical cancer is relatively rare, particularly in women who have not engaged in sexual intercourse. The risk factors for cervical cancer primarily include persistent infection with high-risk strains of human papillomavirus (HPV), smoking, and a weakened immune system. Since you have not had sexual intercourse, the likelihood of cervical cancer is significantly reduced.

The irregular sleep patterns you mentioned could also contribute to hormonal imbalances, which may exacerbate your symptoms. Sleep is crucial for hormonal regulation, and disruptions can lead to increased stress levels and further hormonal fluctuations. It might be beneficial to establish a more regular sleep schedule, as this can help your body regulate its hormonal cycles more effectively.

Given your ongoing symptoms, it may be worthwhile to consider a few steps:
1. Follow-Up with Your Doctor: Since you have experienced prolonged bleeding and irregular cycles, it’s essential to maintain open communication with your healthcare provider. Discuss your symptoms in detail, including the frequency and duration of your bleeding, and express your concerns about potential underlying conditions.

2. Consider a Comprehensive Evaluation: If you haven’t already, ask your doctor about the possibility of a pelvic exam and Pap smear. These tests can provide additional information about your cervical health and help rule out any abnormalities.

3. Lifestyle Modifications: Focus on maintaining a healthy lifestyle, including a balanced diet, regular exercise, and adequate sleep. These changes can help manage PCOS symptoms and improve overall well-being.

4. Monitor Your Symptoms: Keep a detailed record of your menstrual cycle, including the duration and flow of bleeding, any associated symptoms (like pain), and any lifestyle changes. This information can be invaluable for your healthcare provider in determining the best course of action.

5. Seek Support: If you find that your anxiety about your health is overwhelming, consider speaking with a mental health professional. They can help you develop coping strategies to manage your fears and stress.

In conclusion, while your symptoms are concerning, they are not uncommon among women with PCOS. With appropriate medical guidance and lifestyle adjustments, it is possible to manage your symptoms effectively. Remember, staying informed and proactive about your health is key to navigating these challenges.
