A stretched leucorrhea does not necessarily mean ovulation. Leucorrhea is a physiological phenomenon unique to women, and the nature of leucorrhea varies during different menstrual cycles. During ovulation, the leucorrhea will be egg-white like and appear to be stretched, but to determine whether or not you are ovulating, you should follow your menstrual cycle and not rely on the nature of the leucorrhea alone. If you are not able to predict your menstrual cycle, you can go to the hospital to monitor the development of the follicles regularly. When the follicles are mature and have a diameter of about 18-24mm, having intercourse during ovulation can increase the chances of pregnancy. It may also be caused by gynecological inflammation and may be accompanied by vaginal itching and unpleasant odor.
