The package contains 10 disposable tests
Natural Cycles can be used to plan a pregnancy. After ovulation, your temperature rises due to the release of the hormone progesterone. If conception occurred, progesterone continues to be produced to help with the development of the fetus. Thus, you will see your temperature remain elevated even after your expected period. Natural Cycles recognizes that conception has occurred and will prompt you to take a pregnancy test for confirmation. Once you indicate a positive pregnancy test, your temperatures after ovulation will change to blue.
