If there is fluid flow at the time of ovulation, it is basically normal clinically, mainly because the vaginal discharge increases at the time of ovulation. This discharge is similar to egg white and is particularly well stretched. In addition, it is also normal to have vaginal fluid discharge before menstruation, because vaginal discharge increases before menstruation, mainly because of the endometrial glands secretion, so it is also normal, but the color of the discharge is milky white. If there is fluid flow from the vagina at other times, it is clinically understood to be caused by increased vaginal discharge. Increased vaginal discharge is often related to the following factors: 1) vaginal inflammation, 2) cervical inflammation, 3) endometrial inflammation, pelvic inflammation, 4) cervical cancer, endometrial cancer, and fallopian tube cancer, all of which may lead to a large amount of watery vaginal discharge.
