You should begin testing at least 3 to 4 days before your estimated ovulation date to catch the surge. One line is the control line. This is just to let you know that the test is working properly. The other line is the test line. You can tell that LH is surging when this second line is as dark or darker than the control line. Keep in mind that you can get a positive result on your test for several days, so if your first day of testing is positive, next month you may want to test a day or two earlier to ensure you catch the start of your LH surge.
As mentioned earlier, your fertile window begins a few days before the surge, so knowing when it happens can help pinpoint your timing. There are many different types of ovulation test strips — and a range of prices to go along with them! More expensive options offer a digital display, and some detect both estrogen and LH. This allows them to detect more fertile days than some of the basic tests. Whether these test strips will work for you depends on your comfort with reading them.
To make this easier, some brands offer an app to track your tests and compare the lines over time. Read more about the best ovulation tests here. Once baby fever hits, it can be hard to wait! Before skipping to more invasive procedures, though, you may want to consider giving ovulation test strips a try. They can use blood tests to determine your fertile period, or maybe even do a transvaginal ultrasound to check your uterus and ovaries.
Your doctor can offer further assistance or direct you to a fertility specialist. Trying to get pregnant? There are some pros and cons to each.
Strip-based tests like the Modern Fertility Ovulation Test : Ovulation test strips are dipped into a cup of urine for approximately five seconds.
With strip-based tests, you have total control over how much of the strip is exposed to urine, and for how long. If you prefer the packaging for midstream and the ability to cover the strip while waiting for the result, this could be the option for you. Tests differ in terms of how LH is quantified. The ways LH is quantified in ovulation tests fall into two major classes — and these tests can be either strip-based or midstream. Hooray for choices! They can give you a better idea of how your LH is changing over time, help you understand LH patterns, and can pinpoint your most fertile days.
For those with lower or higher baseline hormone production like people with hypothalamic amenorrhea or PCOS , there may be inaccurate readouts.
Our pick is semi-quantitative tests because they give you more detailed information about your hormone levels and get around some of the limitations of threshold-based tests. That brings us back to the Modern Fertility Ovulation Test. We designed our semi-quantitative test to track your unique LH.
Then, your result then matches to low, high, or peak levels on the test pouch to map a unique LH curve. Our test also works like magic with our free app to help you track your LH levels so that you can predict ovulation. You can decide if you want an analog or digital readout of the results. This does mean the user has to do some interpreting — which can sometimes be hard to do accurately.
Digital: For users who would rather have the results of tests interpreted for them and avoid misinterpretation, there are digital readouts, also sometimes called ovulation monitors. But this convenience and technology comes at a cost: Digital tests are more expensive than analog tests. And while using digital tests does take the guesswork out of interpreting an ovulation test result, this technology can sometimes be faulty — some digital tests have even been pulled off the market.
The Modern Fertility Ovulation Test is analog to increase accuracy and save you on costs — but we have a free app that works magic with our app to help you track your LH levels and find your two most fertile days so that you can predict ovulation. If you're not into apps , we also include a handy color chart with your test to make interpreting your results super easy. The exact guidelines for how you should use ovulation tests depend on how regular and long your cycles are.
In these cases, ovulation test manufacturers recommend starting to test a couple of days before the anticipated day of ovulation. If this sounds like you, the conservative approach would be to start testing a couple of days after your period ends and to continue testing until you get indications that ovulation is coming up. For example, for our Ovulation Test , we recommend you start testing 19 days before the start of your period.
Regardless of when in your cycle you start using ovulation tests and which type of test you use, the way you use them should be similar and consistent. Though ovulation tests are likely better than the other cycle-tracking measures, you might be wondering: How good are they?
Luckily, manufacturers of many tests will provide numbers on two key metrics — positive predictive value the percent of people who are ovulating when the ovulation tests tells them they are and negative predictive value the percent of people who are not ovulating when the ovulation tests tells them they are not — to give us an idea of how accurate a test is. There are ways to increase the positive predictive value of ovulation tests, though.
