Understanding unusual vaginal odor can be a complex issue, as it may stem from various causes, including infections, hormonal changes, or even lifestyle factors. The presence of a strong menstrual-like odor, especially when you are not menstruating, can be concerning and warrants further investigation.

Firstly, it is essential to understand that the vagina has a natural flora composed of bacteria that help maintain a healthy environment. Any disruption in this balance can lead to an increase in odor. Common causes of unusual vaginal odor include:
1. Bacterial Vaginosis (BV): This is one of the most common causes of abnormal vaginal odor. BV occurs when there is an overgrowth of certain bacteria in the vagina, leading to a fishy smell, especially after intercourse. It is not a sexually transmitted infection but is associated with sexual activity.

2. Yeast Infections: While yeast infections typically present with a thick, white discharge and itching, they can also cause an unusual odor. The smell may not be as pronounced as with BV but can still be noticeable.

3. Hormonal Changes: Fluctuations in hormones, such as those occurring during the menstrual cycle, pregnancy, or menopause, can affect the vaginal environment and lead to changes in odor.
4. Foreign Objects: Sometimes, a forgotten tampon or other foreign object can cause a foul odor due to bacterial growth.

5. Poor Hygiene: While you mentioned that you wash regularly, it’s important to ensure that you are cleaning the area properly without using harsh soaps or douches, which can disrupt the natural balance of bacteria.

6. Sexually Transmitted Infections (STIs): Certain STIs can also lead to unusual odors. If you have had unprotected sexual contact, it may be worth considering testing for STIs.

Given that you have already consulted a gynecologist and undergone an ultrasound without finding any issues, it may be beneficial to seek further evaluation. Here are some steps you can take:
- Follow-Up with a Specialist: If your symptoms persist, consider returning to your gynecologist or seeking a second opinion. You may also want to ask for specific tests, such as a vaginal swab, to check for infections like BV or yeast infections.

- Maintain Proper Hygiene: Continue to practice good hygiene by washing the external genital area with mild soap and water. Avoid using scented products, douches, or harsh soaps that can irritate the area.

- Monitor Your Symptoms: Keep track of any additional symptoms you may experience, such as changes in discharge, itching, or discomfort. This information can be helpful for your healthcare provider.

- Consider Lifestyle Factors: Diet, stress, and overall health can impact your vaginal health. Ensure you are eating a balanced diet, staying hydrated, and managing stress effectively.

- Probiotics: Some studies suggest that probiotics may help restore the natural flora of the vagina. You might consider incorporating probiotic-rich foods into your diet, such as yogurt or fermented foods.

In conclusion, while unusual vaginal odor can be concerning, it is often manageable with the right approach. It is crucial to communicate openly with your healthcare provider about your symptoms and any changes you notice. They can help guide you toward the appropriate tests and treatments to address your concerns effectively. Remember, your health is paramount, and seeking help is a positive step toward finding a solution.
