This will help you identify the two days of the month when you're most likely to get pregnant.There are changes in your body right before an egg is released from the ovary (ovulation). Ovulation tests work by detecting one of these changes， specifically the increase of luteinizing hormone (LH) levels in urine. The LH surge， as it is commonly called， precedes ovulation by 24 to 36 hours. Predicting your LH surge with an ovulation test enables you to identify the most fertile time of your cycle — the two days beginning with your surge. The Ovulation Test Strips are over 99% accurate (in laboratory testing) in detecting your LH surge.You can maximize your chances of becoming pregnant if you have intercourse within 24 to 36 hours after detecting your LH surge. Timing is one of the most important factors when you're trying to get pregnant.How to use:You will need to determine the length of your menstrual cycle， and work out which day of your cycle to start testing on.For example - if you're cycle is usually 27 days long， you will start testing on day 10 following the start of your previous cycle.You will need to do one test a day until the test indicates that you have an increased amount of LH.Package included:10 x Ovulation test StickNoteHow long will it take before I can read the result?You can read the results in under 5 minutes and a positive result can often be seen in under 30 seconds. However， the full reaction time of 10 minutes is required to confirm a negative result.What should I do with my results?If your pregnancy test results are positive， you should consult your doctor to discuss your pregnancy and what steps and precautions should be taken next. In addition， if your test is negative and you still suspect you may be pregnant， you may want to confirm your test results with another pregnancy test a few days laterIf I see 2 lines but one is fainter than the other is this a positive result?Yes， if 2 lines appear you are pregnant no matter how faint the lines appear. Our 10mIU tests have been designed to identify very early when you are pregnant and the test line will be fainter than the control line until you have been pregnant for about 4 weeks by which time the test line will be as dark or darker than the control line. This ensures our tests do not give false positives which is very important when you want to know if you are pregnant or not.Can anything affect the results of these tests?Drinking alcohol， painkillers， oral contraceptives， antibiotics and other common drugs will not affect the result of these tests. Only medicines that contain HCG can produce a false positive result. If you are unsure about your result or your period has still not arrived you should see your doctor for advice.
