The time of ovulation after having egg white leukorrhea is irregular. During the menstrual cycle, cervical secretions and vaginal secretions are influenced by the levels of estrogen and progesterone in the body and undergo cyclical changes. Estrogen levels rise to a certain extent, cervical secretions appear thin, egg white-like. After ovulation, progesterone levels increase and cervical secretions become thick. Egg white discharge occurs during ovulation. Most women with regular menstrual periods ovulate about 14 days before their next period, and it is uncertain when exactly they ovulate. Ovulation can be delayed or advanced by environmental, physical and psychological factors. The approximate time of ovulation can be predicted by ultrasound, ovulation test, cervical mucus examination to look for amniotic crystals. Women who need to monitor their ovulation can consult a regular hospital and complete the examination under the guidance of a doctor to predict the time of ovulation.
