Not only does cervical fluid become thinner and stretchier as ovulation approaches, it also becomes more abundant. A woman may not be able to tell if her cervical mucus has changed to the right type of mucus, but she should be able to observe how her body feels.

When she is fertile she will feel wetter and her vagina will feel more lubricated during sex. This is different from the arousal fluid a woman makes. Around ovulation, she will feel wetter throughout the day and not just during intercourse.
