After you determine the best day to start testing based on your monthly cycle, you can use the FIRST RESPONSE™ Ovulation Prediction Tests any time that day. You do not have to use your first morning urine. However, you should do the test about the same time each day. Reduce your liquid for two hours before testing, since drinking excessive amounts of liquid intake can dilute the LH in your urine.
Since not every woman ovulates mid-cycle, you may not detect the LH surge in the first 7 days of testing. This could mean you have not ovulated yet and you should continue testing with additional FIRST RESPONSE™ Ovulation Prediction Tests or start testing a few days earlier next month.
First, it is important to remember that it can take normal, healthy couples many months to become pregnant. There are many factors that affect your ability to become pregnant even if you have been able to have intercourse during your most fertile time. If after several months you have no success, consult your physician. Since you have been monitoring your LH surge with the FIRST RESPONSE™ Complete Pregnancy Planning Kit, you will be able to give your doctor a clearer picture of when you have been ovulating.
Your two most fertile days begin with the LH surge. You are most likely to get pregnant if you have intercourse within 24-36 hours after you detect your LH surge.
Only medications containing the pregnancy hormone (hCG) can affect the result of the test. The test should not be affect by hormone therapies containing Clomiphene citrate, alcohol, pain killers, antibiotics, or the contraceptive pill. Please consult your healthcare professional if you are taking any medications.
After using the pill your cycle may be irregular and make take some time to stabilise again. You may wish to wait until you have had two normal periods before starting to use the FIRST RESPONSE™ Complete Pregnancy Planning Kit. Follow your physician’s advice on when to best try to become pregnant.
Sperm can survive up to 72 hours (3 days), and this test predicts your LH surge only up to 24-36 hours in advance. Therefore, if you have intercourse before you discover your surge, the egg can still be fertilised.
