Postcoital bleeding


After engaging in sexual intercourse, I have experienced bleeding for about three days now, and it continues.
The blood is bright red and there is no pain.
I have already visited a gynecologist, but the bleeding persists, especially increasing during walking or physical activity.
I would like to ask how long this type of bleeding usually takes to resolve.
Are there any specific precautions or restrictions I should be aware of? Thank you!

Wishing you good health.

More Info


Post-sexual bleeding can be a concerning symptom for many individuals, and understanding its causes, duration, and when to seek medical help is crucial for managing your health effectively. Based on the information provided, it appears that you have been experiencing bright red bleeding for approximately three days following sexual activity, with an increase in blood flow during physical activity.

Possible Causes of Post-Sexual Bleeding
1. Trauma or Injury: One of the most common causes of post-sexual bleeding is trauma to the vaginal walls or the cervix. This can occur due to vigorous sexual activity, insufficient lubrication, or even the use of fingers or objects during sexual play. The delicate tissues in the vaginal area can easily become irritated or torn, leading to bleeding.

2. Hormonal Fluctuations: Hormonal changes throughout your menstrual cycle can also contribute to bleeding. For instance, if you are close to ovulation or menstruation, your cervical mucus may be more abundant, and the cervix may be more sensitive, increasing the likelihood of bleeding.

3. Infections: Infections such as sexually transmitted infections (STIs) or bacterial vaginosis can cause inflammation and irritation, leading to bleeding after sexual activity. If you have any accompanying symptoms like unusual discharge, itching, or burning, it’s important to get tested.

4. Cervical or Uterine Issues: Conditions such as cervical polyps, fibroids, or even cervical cancer can cause abnormal bleeding. If the bleeding persists or is accompanied by other symptoms, further investigation may be necessary.

5. Endometriosis: This condition, where tissue similar to the lining inside the uterus grows outside of it, can cause pain and bleeding during or after sex.


Duration and Recovery
The duration of bleeding from minor trauma can vary. Typically, if the bleeding is due to a small tear or abrasion, it may resolve within a few days to a week. However, if the bleeding continues beyond this period or increases in volume, it is essential to seek medical attention.

When to Seek Help
You should consider seeking medical help if:
- The bleeding persists for more than a week.

- You experience significant pain or discomfort.

- There is a foul odor associated with the bleeding.

- You have fever or chills, which could indicate an infection.

- The bleeding is heavy enough to soak through a pad or tampon in an hour.


Recommendations and Precautions
1. Avoid Sexual Activity: Until the bleeding resolves, it may be wise to refrain from sexual activity to allow any potential injuries to heal.

2. Monitor Symptoms: Keep track of any changes in your bleeding pattern, including the amount, color, and any accompanying symptoms like pain or discharge.

3. Use Lubrication: If you resume sexual activity, consider using a water-based lubricant to reduce friction and minimize the risk of further injury.

4. Follow Up with Your Doctor: Since you have already seen a gynecologist, it’s important to follow up if the bleeding continues. They may recommend further tests such as a pelvic exam, ultrasound, or Pap smear to rule out any underlying conditions.

In conclusion, while post-sexual bleeding can often be attributed to minor injuries or hormonal changes, persistent or severe symptoms warrant further investigation. Always prioritize your health and do not hesitate to seek medical advice when in doubt.
