Brown discharge the day after intercourse has persisted for two weeks?


The menstrual cycle lasts about 6-7 days, with a cycle length of approximately 24-26 days.
I had unprotected intercourse on the 10th and 11th, and there was also manual stimulation with ejaculation.
On the morning of the 12th, when I went to the bathroom, I noticed a small amount of brown discharge on the toilet paper, which I am unsure if it is blood or discharge.
The amount was very minimal, only requiring a panty liner, and it has been two weeks since then.
The doctor prescribed progesterone, which I have been taking for three days, but there is still a slight discoloration.
The doctor mentioned it is to regulate my cycle, but I have never experienced irregular periods before.
I would like to know if this could be due to vaginal injury or uterine issues.
This is not my first time having intercourse, and I have never been pregnant, and my lifestyle is normal.

More Info


Brown discharge after intercourse can be concerning for many individuals, and it’s important to understand the potential causes and implications of this symptom. The brown color typically indicates old blood, which may be a result of various factors related to the menstrual cycle, hormonal changes, or physical trauma.

Possible Causes of Brown Discharge
1. Menstrual Cycle Variations: It is not uncommon for women to experience brown discharge at different times in their cycle. This can occur at the beginning or end of a menstrual period when the flow is lighter, and the blood takes longer to exit the body, resulting in a brown color.
2. Ovulation: Some women experience spotting during ovulation, which can also appear brown. This is due to the hormonal fluctuations that occur around the time of ovulation.

3. Hormonal Imbalance: Hormonal changes, especially those related to the luteal phase of the menstrual cycle, can lead to brown discharge. If you have been prescribed progesterone (like the yellow hormone you mentioned), it may be an attempt to regulate your cycle, but it can also cause some spotting as your body adjusts.

4. Physical Trauma: If there was any vigorous activity during intercourse, it could lead to minor trauma to the vaginal walls or cervix, resulting in light bleeding that appears brown. This is more likely if there was insufficient lubrication or if the intercourse was particularly intense.

5. Infections: Certain infections, such as sexually transmitted infections (STIs) or bacterial vaginosis, can cause abnormal discharge, including brown discharge. These infections may also be accompanied by other symptoms like itching, burning, or an unusual odor.

6. Cervical or Uterine Issues: Conditions such as polyps, fibroids, or endometriosis can cause irregular bleeding or discharge. If the discharge persists or is accompanied by pain, it is essential to consult a healthcare provider for further evaluation.


When to Seek Medical Attention
While brown discharge can be normal, it is crucial to monitor the situation. If you experience any of the following, you should seek medical advice:
- The discharge continues for an extended period (more than a few days).

- There is a significant change in the amount or color of the discharge.

- You experience pain during intercourse or unusual abdominal pain.

- There are other symptoms like fever, chills, or unusual odor.


Conclusion
In your case, since you have a regular menstrual cycle and have not experienced this symptom before, it could be related to the recent hormonal treatment or possibly minor trauma from intercourse. It is advisable to keep track of your symptoms and consult with a healthcare provider if the discharge persists or if you have any concerns. They may perform a pelvic examination, consider your medical history, and possibly conduct tests to rule out any underlying issues.
Remember, while some variations in discharge can be normal, it’s always best to err on the side of caution and seek professional advice when something feels off.
