Description

Ovulation is the release of an egg from the ovary, when the egg reaches the fallopian tube it is ready to be fertilized. In order for pregnancy to occur the egg must be fertilized by sperm within 24 hours after its release. Immediately prior to ovulation the body produces a surge of Luteinizing hormone (LH) – this usually takes place in the middle of the menstrual cycle. LH triggers the release of the egg from the ovary. Clear & Simple Ovulation tests detect the LH surge in urine, signalling that ovulation is likely to occur in the next 24-48 hours. During this period of ovulation you are at your peak fertility. It is during this most fertile time that pregnancy is most likely to occur if you have sex.

What are ovulation tests used for?

Most people use ovulation tests to track ovulation so that they know when the best time is to try for a baby. Some people use ovulation testing as a natural form of contraception so that they know when to avoid sex. It is not a totally reliable form of contraception but is recommended by some religions opposed to contraception and is sometimes called the rhythm method.

If you don’t know your cycle length you are advised to wait for at least one menstrual cycle and note the length of the cycle before using this test. If you want to start without knowing your cycle length you may begin the test 11 days after the first day of your period as the average cycle length is 28 days. Perform 1 test at approximately the same time each day over a 5 day period or until the LH surge has been detected.

A positive test result shows that the LH surge has been detected. Your 2 most fertile days are today and tomorrow so if you have sex in the next 48 hours you will maximise your chance of getting pregnant. If your result is negative, retest at the same time each day until you detect your LH surge. If your cycle length varies by more than 3 days, it is possible that you will need to start a new pack to detect your LH surge. Some women do not ovulate each cycle and will not have a LH Surge.
