Most women will have stretched leukorrhea during ovulation, but they may not have stretched leukorrhea. Because most women have the highest estrogen levels during ovulation, they will have increased leucorrhea and increased lacrimation, but a small number of women may not ovulate and their estrogen levels will decrease, so they may not have lacrimation and they will not have lambdoid crystals in their leucorrhea. Ovulation is usually about two weeks before the next menstrual period, but there is some variation. If a woman has a need for pregnancy, she can use ovulation test strips to monitor ovulation, because having sex during ovulation can significantly increase the probability of conception. You need to change your underwear regularly, as increased leukorrhea can easily lead to too much local moisture, which can then easily lead to the growth of pathogenic bacteria and thus infection.
