More often than not, a woman is only fertile for 4 to 5 days during their cycle. In fact, the egg which is released will only live for 12 to 24 hours and sperm only retain fertilising power for around 3 days. Ovulation tests have been created to detect your 2 most fertile days. They are also really useful for knowing the best time to conceive and optimise your chances of getting pregnant.
How does an ovulation test work? It detects the peak of the luteinising hormane, which is most prevalent 24 to 36 hours before ovulation. So, if the ovulation test is positive and you wish to become a parent, you must have intimate relations within 48 hours.
Clearblue is one of the most well-known brands for pregnancy and ovulation tests. Over 99% reliable, the ClearBlue Test of Ovulation Digital has the advantage of being simple to use and easy to read.
