Clear vaginal fluid is common for the following reasons: 1. Clear vaginal discharge that appears only in the middle of two menstrual cycles is a manifestation of leukorrhea during ovulation and is a physiological reaction, not accompanied by other conscious symptoms. 2. Clear discharge that appears after sexual intercourse is considered to be caused by an allergic reaction to the condom used or to the semen that enters the vagina, and there is a significant increase in the discharge. 3. Clear discharge that is not related to menstruation or sexual intercourse may be caused by benign gynecological tumors such as uterine fibroids and ovarian cysts. 4. It may also be caused by diabetes, abnormal thyroid function or severe anemia.
