How to Use a Saliva Ovulation Predictor Kit. Saliva Ovulation Predictors (Saliva Fertility Tests) When a woman is about to ovulate, her saliva begins to form a distinct fern-like pattern due to an increase in the level of salt and estrogen. This visible ferning pattern begins to appear around 3 to 4 days prior to ovulation. Ovulation microscopes – or saliva fertility tests – allow you to predict ovulation by viewing the changes in the make up of your saliva prior to ovulation.With the saliva-based ovulation fertility tests, just add a drop of saliva to the lens and let the sample dry. In five minutes, view the sample through the microscope. Note for new users:Remember that you need to press the LED light button and focus by turning the eyepiece of the microscope. If you are ovulating – or about to ovulate – a ferning, crystal-like pattern can be identified when examined under the power of the microscope, helping you predict fertile or infertile times in your cycle.
