A common misconception with ovulation tests is that they tell you specifically when you are ovulating, which sadly isnât true. Ovulation predictor kits actually work by testing for the luteinizing hormone (LH) which is the indicator of your body preparing to release a matured egg.
Testing your hormone levels with an ovulation predictor kit (OPK) is another method. There are two kinds of kits: The most common type tests your urine, and the other tests your saliva. Both show a positive result in the days before you ovulate, giving you time to plan ahead for baby-making sex.
