Vulvar edema during ovulation is a common phenomenon that usually occurs a few days before ovulation, especially in the afternoon. Although this phenomenon is uncommon, it may have consequences for pregnancy or reproductive health.

Vulvar edema can be caused by a variety of reasons, including:

1. Changes in hormone levels in the body: During the ovulation period, a woman’s hormone levels in the body will change, causing the body to be unable to effectively absorb and discharge water, thereby aggravating vulvar edema.

2. Vaginal flora imbalance: If the vaginal flora is imbalanced, it may lead to vaginal inflammation and aggravate vulvar edema.

3. Malnutrition: Malnutrition may also lead to vulvar edema.

4. Other diseases: Some other diseases, such as heart disease, high blood pressure, diabetes, etc., may also cause vulvar edema.

Although vulvar edema is uncommon, it may have consequences for pregnancy or reproductive health. If you find that you have vulvar edema, you should take timely measures, such as checking your physical health, adjusting your diet and lifestyle, etc., to avoid negative impacts on pregnancy or reproductive health.

Finally, it should be noted that if vulvar edema is caused by a disease, you should seek medical treatment in time and receive professional treatment.
