Postcoital bleeding


Hello doctor, my menstrual cycle is usually very regular.
This month, my period started on October 9th and typically lasts for three days with lighter flow afterward, finishing by the 17th.
However, due to some issues with my husband, we had intercourse every day from the 16th to the 21st, even though my period wasn't completely over on the 16th.
Previously, I would have intercourse about 4-5 times a month.
During this period, I also stayed up late, around 1-2 AM, and was crying, while needing to wake up at 6 AM for work.
After intercourse on the 21st, I noticed some clear, white, sticky discharge with blood streaks in the afternoon, and felt a strange sensation in my abdomen.
Later that night, I found dried blood on my underwear.
My abdomen felt bloated.
Last year, I experienced irregular bleeding outside of my menstrual cycle that lasted five days, with only a drop or two of blood.
I underwent a hysteroscopy last year, and the doctor said my endometrium was normal, attributing it to irregular menstruation.
However, the bleeding on the 21st was more than just a drop or two.
On the 22nd, I didn't see any bleeding, but I felt something unusual in my right abdomen.
Could this vaginal bleeding be due to vaginal inflammation, or is it just irregular menstruation?

Hello, I'm sorry but I cannot diagnose based on the described symptoms.
It could be ovulatory bleeding.
If you continue to feel unwell, I recommend seeing a gynecologist for an examination.
Wishing you good health.

Understanding post-intercourse bleeding can be quite concerning, especially when it deviates from your normal menstrual pattern. Based on your description, it seems you experienced a regular menstrual cycle that ended on October 9th, followed by a period of increased sexual activity from October 16th to 21st. The subsequent bleeding you observed, particularly the presence of blood in your discharge and the changes in your abdominal sensations, raises a few potential explanations.

Firstly, it’s important to consider the possibility of hormonal fluctuations. Stress, changes in sleep patterns, and increased sexual activity can all contribute to hormonal imbalances. In your case, the emotional stress from relationship issues, combined with late nights and early mornings, could have disrupted your normal hormonal cycle, leading to irregular bleeding. This is often referred to as dysfunctional uterine bleeding, which can occur when the hormonal signals that regulate your menstrual cycle are out of sync.

Another potential cause for the bleeding could be cervical irritation or inflammation. During intercourse, especially if there is increased friction or if the cervix is sensitive, it can lead to minor trauma or irritation, resulting in light bleeding. The presence of white, transparent discharge with blood streaks could indicate that the cervical tissue was slightly damaged or inflamed. This is particularly common if there has been a change in sexual activity frequency or intensity.

Additionally, vaginal infections or inflammation could also be a factor. Conditions such as vaginitis or cervicitis can cause abnormal discharge and bleeding. If there is an infection, it may also be accompanied by other symptoms such as itching, burning, or unusual odor. Given your history of a normal endometrial biopsy, it is less likely that there are significant structural issues, but infections should still be ruled out.

Since you mentioned that you had a similar experience last year, it’s worth noting that recurrent episodes of post-coital bleeding can sometimes indicate underlying conditions such as polyps or fibroids, although these are less likely given your previous normal examination results. However, if the bleeding persists or worsens, it would be prudent to consult with a healthcare provider for further evaluation.

In summary, the bleeding you are experiencing could be attributed to a combination of hormonal changes due to stress and lifestyle factors, cervical irritation from increased sexual activity, or potential infections. If the bleeding continues, or if you develop additional symptoms such as severe pain, fever, or changes in discharge, it is essential to seek medical attention. A healthcare provider may recommend a pelvic examination, ultrasound, or further testing to determine the exact cause of your symptoms and provide appropriate treatment.
In the meantime, try to manage stress through relaxation techniques, maintain a regular sleep schedule, and monitor your symptoms closely. Keeping a diary of your menstrual cycle, sexual activity, and any symptoms can also be helpful for your healthcare provider in diagnosing the issue.
