The First Response Ovulation Test will help you find the time that you are most able to become pregnant. It can also help you plan your pregnancy.
The test measures luteinising hormone (LH), which is always present in your urine and increases just before your most fertile day of the month. This increase, or 'surge', in LH triggers ovulation which is the release of an egg from an ovary.
The appearance of two easy-to-read purple lines in the test's Result Window indicates your LH surge prior to ovulation. Most women will ovulate within 24 to 36 hours after the LH surge is detected. Predicting ovulation in advance is important because the egg can be fertilised only 6 to 24 hours after ovulation. Your two most fertile days begin with the LH surge. You are most likely to become pregnant if you have intercourse within 24 to 36 hours after you detect your LH surge.
You may test at any time of the day, but you should test at approximately the same time each day and reduce your liquid intake for 2 hours before testing.
To find out when to begin testing, determine the length of your normal cycle. The length of your cycle is from the beginning of one period to the beginning of the next. Count the first day of bleeding or spotting as day 1.
If your cycle is irregular, that is, if it varies by more than a few days each month, take the average number of days for the last 3 months. Use the chart to work out the day you should begin testing. The day you begin testing is listed below the number of days in your normal cycle. For example, looking at the chart, if your period normally begins every 28 days, you should begin testing 11 days from the beginning of your last period.
If you are having difficulty becoming pregnant it could be that you are not making love in the 2 days, around the time of ovulation, when you are most fertile. First Response Ovulation Test will help you identify these days by detecting the rapid increase in luteinising hormone (LH surge) which normally occurs before ovulation.
First Response Ovulation Test contains five simple tests - use them on the days around your mid-cycle to identify the increase in luteinising hormone. Your two most fertile days begin with the LH surge. You are most likely to become pregnant if you make love within 24-36 hours after you detect your LH surge.
