Increased leucorrhea is not necessarily a precursor to menstruation, but it can occur before menstruation. When menstruation is imminent, the uterus and cervix tend to become congested and edematous, which can lead to increased discharge. Increased leukorrhea can also occur at other times, such as during ovulation, pregnancy, and during sexual intercourse. During ovulation or pregnancy, estrogen increases in the body, which can easily stimulate increased discharge, so increased leucorrhea does not necessarily mean that you are about to have your period, it could be during ovulation or pregnancy. If there are gynecological infections, such as vaginitis, cervicitis, endometritis, pelvic inflammatory disease, etc. will also cause increased leucorrhea. Increased leucorrhea with gynecological infections can also cause vulvar itching as well as foul odor and other odors from the vulva. It is advisable to have a routine examination of the leucorrhea and also an ultrasound examination, and after identifying it, use reasonable medication to regulate it and pay attention to vulva hygiene.
