There is no direct correlation between a woman experiencing swelling of the vulva during ovulation, as ovulation does not normally cause swelling of the external cause. The main changes that may occur in women during ovulation are an increase in estrogen levels, an increase in luteinizing hormone levels, and ovulation in the patient. Due to the changes in hormone levels, this can cause a woman to have an increased amount of vaginal discharge that is thin and easy to draw, but it will not be abnormal in color, odor, or vulvar discomfort. If a woman experiences swelling of the vulva or vagina during ovulation, it is mainly considered that it may be caused by inflammatory diseases, allergic diseases or other reasons such as trauma, which has nothing to do with this special stage of ovulation, and the patient should go to the hospital in time to have a relevant examination, and then symptomatic treatment.
