Most women will have their menstruation in about half a month after they have a stretched leucorrhea. It usually happens during ovulation, because the hormonal influence of ovulation increases the vaginal secretions and there is a lot of cervical mucus in the leucorrhea, which causes the leucorrhea to become sticky and stretched, and the longest stretch can reach about 10cm. The stretched leucorrhea is also very conducive to the passage of sperm and can be used as an indicator of ovulation. Ovulation usually occurs on the 14th-16th day before the next menstrual period, so most women will have their period in about half a month after the typical white ribbon straining symptoms appear. During this period, you can prepare for pregnancy if you have fertility requirements.
