More than just Ovulation Tests

The Pearl Kit includes FSH and LH tests, and some also Progesterone tests. These are the three main hormones that regulate your cycle and ovulation date. The Pearl App can measure FSH, LH and Progesterone tests individually and gives you a personalized report, rather than a one-fits-all calendar or temperature method.

Know the hormones!
