Comment le test fonctionne-t-il ?

Ovulation tests predict when you ovulate, i.e. when your ovaries release an egg and you are most likely to get pregnant. This test measures elevated levels of luteinising hormone (LH) in your urine. LH is a hormone that increases 24 to 48 hours before ovulation. You are most fertile on the day of the LH surge and the following two days.
