Ovulation Predictor Tests - or OPKs - allow you to accurately pinpoint your most fertile time of the month.
They work by allowing you to detect your "LH Surge" - the dramatic increase in luteinising hormone present in your urine just before you ovulate.
Luteinising hormone in elevated quantities causes ovulation.
During a normal menstrual cycle only a small amount of LH is made, but in the middle of a normal cycle LH briefly increases.
Conception is most likely to occur within thirty-six hours following the LH surge.
Increase your chances of conception with reliable and affordable Ovulation Predictor Strips.
Simply collect a urine sample in a clean cup and dip the ovulation predictor test strip into the urine for a few seconds.
Accurate, easy to read results appear in just 5 minutes.
