Unusual Odor After Miscarriage: Causes and Concerns for Women

Odor after a miscarriage?

Approximately at the end of last year, I became pregnant.
At 4 weeks, no embryo was visible.
Later, on January 25, I experienced a blood clot.
Upon follow-up, the embryo was still not visible, and after testing HCG, it was confirmed that I had a miscarriage.
The doctor mentioned that everything had cleared out.
I continued to experience bleeding until February 24, when the doctor indicated that it was bleeding due to hormonal imbalance (I have polycystic ovary syndrome).
I was prescribed progesterone and hemostatic medication.
After taking it for a week, the bleeding did not stop.
On March 9, my menstrual period started (with pain and flow similar to my regular period), and the bleeding completely stopped a week later.
After confirming that there was no bleeding for three days, I engaged in sexual intercourse.
However, during intercourse, there was a slightly fishy odor with a hint of blood.
Sometimes, the discharge appears yellowish.
I would like to know if the odor is due to not being fully healed or if there is an infection.
Aside from the odor, I have no other symptoms.
Thank you for your response!

More Info

Experiencing unusual odors after a miscarriage can be concerning for many women, and it’s important to understand the potential causes and implications. In your case, it seems you went through a miscarriage and have been experiencing some unusual symptoms afterward, including a foul odor during sexual intercourse and yellowish discharge. Let’s break down the possible causes and concerns regarding these symptoms.

Possible Causes of Unusual Odor After Miscarriage
1. Incomplete Miscarriage: Although your doctor mentioned that everything was cleared out, there is a possibility that some tissue might still be retained in the uterus. This retained tissue can lead to an infection, which may produce a foul odor. It’s essential to follow up with your healthcare provider if you suspect this might be the case.

2. Infection: The presence of a foul odor, especially if accompanied by unusual discharge (like yellowish discharge), could indicate an infection. Common infections following a miscarriage include endometritis (infection of the uterine lining) or pelvic inflammatory disease (PID). These infections can occur due to retained products of conception or from bacteria entering the uterus during or after the miscarriage.

3. Hormonal Changes: After a miscarriage, especially in women with conditions like polycystic ovary syndrome (PCOS), hormonal fluctuations can lead to irregular bleeding and changes in vaginal discharge. This can sometimes alter the smell of the discharge, but it typically wouldn’t cause a strong foul odor.

4. Normal Post-Miscarriage Changes: After a miscarriage, the body goes through a healing process, which can include changes in vaginal discharge. However, this should not typically include a strong, unpleasant odor. If the odor is persistent or worsening, it’s a sign to consult your healthcare provider.

Concerns and Recommendations
- Seek Medical Attention: Given your symptoms, it’s advisable to consult your healthcare provider. They may perform a pelvic exam and possibly an ultrasound to ensure there are no retained tissues and to check for signs of infection.

- Monitor Symptoms: Keep track of any additional symptoms you may experience, such as fever, increased pain, or changes in discharge color or consistency. These could indicate a more serious issue that requires prompt medical attention.

- Follow-Up Care: Since you have a history of PCOS, it’s crucial to maintain regular follow-ups with your healthcare provider to monitor your hormonal levels and overall reproductive health. This is especially important after a miscarriage, as your body may take time to return to its pre-pregnancy state.

- Hygiene Practices: Maintain good hygiene practices, especially during this recovery period. Avoid using douches or scented products in the vaginal area, as these can disrupt the natural flora and potentially lead to infections.

Conclusion
In summary, while some changes in odor and discharge can be normal after a miscarriage, a persistent foul odor is concerning and warrants further investigation. It’s essential to communicate openly with your healthcare provider about your symptoms and any worries you may have. They can provide the necessary examinations and treatments to ensure your recovery is on track and to address any potential infections or complications. Remember, your health and peace of mind are paramount, so don’t hesitate to seek help when needed.
