The most used signs are a normal discharge of cervical mucus and other signs include changes in her cervix and a feeling called “ovulation pain”.
Cervical mucus is nature’s way of helping a man’s sperms reach a woman’s egg. Her flow of cervical mucus generally starts in a small way several days before she ovulates (releases an egg), it is a very positive sign that her fertile time has started. About the time she ovulates, her mucus may be abundant and have a consistency something like raw egg white. After ovulation, her mucus normally disappears.
