Never before in history have couples who are trying to conceive had so many resources available to them. In addition to the information that they have available at their fingertips, there are a large number of products that can assist with the task of trying to add to their family. One of the most interesting products that has come on the market is an ovulation test, which will actually allow a woman to be able to tell when she is ovulating, in order to maximize the chances of conception.

Ovulation tests help you to know when you are ovulating by testing for the presence of Luteinizing Hormone (also known as LH) in your urine stream. To understand how ovulation tests work, it is important to understand something about how ovulation works. Luteinizing hormone is always present in your urine. SOme time between 24 and 48 hours before you ovulate, however, you will experience an increase in the amount of Luteinizing Hormone that is in your system. This “LH Surge” as it is known actually triggers your body to ovulate.

For an ovulation test to work properly, you have to know for certain when it is that you should be testing for ovulation. Ovulation typically occurs 14 days before the start of your next period. This means that if you have a regular 28-day cycle, you should start ovulating on day 14. The ovulation test would work best on or around day 13 of your cycle. On the other hand, if you have a 30-day cycle, you will not typically start ovulating on day 14. Instead, you will typically start ovulating on day 16, meaning that you would want to use your ovulation test on or around day 15 or so.

Ovulation tests are considered to be very accurate at detecting the surge of Luteinizing Hormone in your system. In fact, when they are used correctly, they are thought to be around 99% accurate at detecting the LH Surge.
