How Ovulation Tests Work
Ovulation tests increase your chances of conceiving by detecting your LH surge – that way you can identify your most fertile time of the month. Ovulation tests help you identify the two days of the month when you’re most likely to get pregnant.
There are changes in your body right before an egg is released from the ovary (ovulation). Ovulation tests work by detecting one of these changes, specifically the increase of luteinising hormone (LH) levels in urine. The LH surge, as it is commonly called, precedes ovulation by 24 to 36 hours. Predicting your LH surge with an ovulation test enables you to identify the most fertile time of your menstrual cycle – the two days beginning with your surge.
You can maximise your chances of becoming pregnant if you have intercourse within 24 to 36 hours after detecting your LH surge. Timing is one of the most important factors when you’re trying to get pregnant. You can predict your two most fertile days in the month with the FIRST RESPONSE™ 7 Day Pregnancy Planning Kit to maximise your chances of becoming pregnant. This kit includes seven ovulation prediction tests and a FIRST RESPONSE™ Early Result In-Stream Pregnancy Test.
