Ovulation test kits help you accurately identify your fertile window by detecting the surge in luteinising hormone (LH) in your urine just before ovulation. This blog explains what ovulation predictor kits are, how they work, and when to start testing based on your menstrual cycle length. It guides you on the right time of day to test, how to collect and use the urine sample, and how to read single-line versus double-line or digital results correctly. By timing intercourse within 24–48 hours after a positive test, couples can significantly improve their chances of conceiving naturally.
