Increase in Libido
Some women experience an increased sexual drive during and around ovulation. [6] The reason why this happened is not clear. It is likely the body giving you a nudge to fertilize your eggs. Increased libido is not a foolproof symptom of ovulation because it can be caused by other factors beyond it.
Changes in Saliva
During ovulation, you may experience changes in the appearance of your saliva. [7] This is particularly true of dried saliva, which may look like crystals or ferns. This symptom is caused by hormonal changes.
Conclusion
Not all women ovulating experience symptoms of ovulation. While some of these symptoms are most commonly associated with ovulation, no symptom is a surefire way to predict ovulation. Pregnancy is most likely to happen during ovulation, but it may also happen a few days before or a day after.
