No cervical mucus during ovulation

Cervical mucus is a type of mucus secreted by cervical gland cells that is continuously secreted during a woman's menstrual cycle. During the ovulation period, the secretion of cervical mucus increases, becomes clear and transparent, and has a thin texture, which is beneficial for sperm to pass through the cervical opening and enter the uterus. If a woman's cervical mucus secretion is insufficient or the quality decreases, she will have no cervical mucus.

Cervical mucus production is affected by many factors, including the menstrual cycle, physical health, hormonal levels, and sexual behavior. If a woman suffers from chronic illness or poor physical health, the amount and quality of cervical mucus will decrease, resulting in no cervical mucus.

In addition, sexual behavior is also an important factor affecting cervical mucus secretion. If a woman does not take effective protective measures during sexual intercourse, it may cause sperm to penetrate the cervix, resulting in the absence of cervical mucus.
