During ovulation, the hormone levels in women’s bodies can reach a peak again, causing the leucorrhea to be stretched, which usually lasts for 2-3 days. It is a phenomenon unique to women during ovulation, which is caused by the increase in the secretion of cervical mucus due to the rise in the level of estrogen in women during ovulation, and the secretion of progesterone after ovulation, which causes the endometrium to be in a secretory state, resulting in a large amount of colorless and transparent vaginal secretions that are thin and easily stretched. This kind of vaginal secretion is moderately acidic and alkaline, which is suitable for sperm activity and facilitates sperm to cross the cervix into the uterine cavity and fallopian tube and meet the egg, which is more conducive to conception. Patients are advised to pay attention to personal hygiene during this period to avoid vaginitis caused by infection due to increased leukorrhea. If you want to accurately determine the ovulation period, you can go to the hospital for ultrasound monitoring or take an ovulation test to better prepare for pregnancy.
