We are so excited to introduce Proov Predict: a pack of 30 LH or ovulation tests so that you can predict ovulation from the comfort of your home!
If you’re familiar with Proov, you know we love talking all things ovulation. After all, our first product is the first and only PdG test kit to confirm successful ovulation at home!
You may also know that we love talking about the “full ovulation picture” — predicting and confirming ovulation. This is why we are so excited to introduce Proov Predict: a pack of 30 LH or ovulation tests (and our signature P Cup!) so that you can predict ovulation from the comfort of your home.
How does Proov Predict work?
Proov Predict kits come with 30 LH tests and our fun P Cup! LH (luteinizing hormone) tests — also known as ovulation tests — are used to detect LH in urine. Before ovulation, a rise in estrogen triggers an LH surge which signals to the ovary to release an egg.
This is important because there are actually only a few days each cycle when conception is possible, known as your fertile window. After an egg is released, it is only viable for up to 24 hours.
However, sperm can live in the female reproductive tract for about 3-5 days. So ideally you’d want sperm present when the egg is released, which is why predicting ovulation is such a critical step when trying to conceive.
Proov Predict allows you to measure your LH levels over time to accurately catch the LH surge that opens your fertile window. Ovulation typically occurs 24-48 hours after an LH surge. With Proov Predict, you can identify your two most fertile days in order to time intercourse around ovulation.

Why should I use Proov Predict?
By now you may be thinking, “Ok, well ovulation happens on cycle day 14 so I’ll just start having intercourse a few days before then.” This is actually a very common misconception in the fertility world!
It’s true that ovulation happens about midway through your cycle. However, an ovulation day of cycle day 14 assumes you have a 28-day cycle. In fact, most women do not have cycles that last exactly 28 days and you can actually ovulate as early as cycle day 8 and as late as cycle day 26.
Using Proov Predict helps you accurately pinpoint your fertile window, regardless of your cycle length. Each woman and cycle is unique, of course!
Understanding when you’re fertile is important if you’re trying to conceive of course, but ovulation is also a sign of overall health. Tracking ovulation with Proov Predict can help you understand your cycle length and if you have an underlying health issues.
Why is Proov Predict different from other LH tests?
First and foremost, Proov Predict comes with a cute, free P cup! (Seriously — it makes peeing in a cup fun!) Even better, Proov Predict saves plastic since our P cup is reusable and our tests are strip-based (meaning they don’t have plastic casing).
Proov Predict was also developed by a U.S.-based, women-owned business. Our founder, Amy, tested over 10 of the leading ovulation test brands to ensure Proov Predict stacked up! Because of this, we know that Proov Predict tests are accurate and provide clear results.

How do I use Proov Predict?
Proov Predict works similarly to your typical ovulation test: you simply collect a urine sample, dip the test strip, and read the results. Like other LH tests, Proov Predict is considered positive when the test line is as dark or darker than the control line. Proov Predict tests are designed to turn positive when 25 mIU/ml of LH is present in urine (the FDA standard).
We recommend starting to test Proov Predict tests 18 days before your next expected period. This means that if you have 28 day cycles, you’ll want to start testing with Proov Predict on cycle day 10. Proov Predict instructions include a handy chart to help you calculate when to start testing.
You’ll likely start testing once per day. Note that first morning urine is not necessary. In fact, some studies show that LH surges begin early in the morning, meaning they won’t be reflected in your urine until later that day.
As you near your suspected ovulation date, you may want to start testing twice per day — once in the morning and once in the afternoon. This is because LH surges can be very short, so if you test at the wrong time of day you may not accurately catch it. Luckily, Proov Predict comes with plenty of tests to allow for testing twice per day!
What should I do once I get a positive LH test?
A positive LH test signifies that LH levels are high and indicates an LH surge. Most women will ovulate within 24-48 hours of a positive LH test, meaning this is the time to “try.” During your fertile window, you should try to have intercourse daily or every other day.
Note that some women (such as those with Polycystic Ovarian Syndrome) will never get a positive LH test. If you never get a positive LH test, we recommend consulting your doctor or trying a different ovulation prediction method.

How do I use PdG tests with Proov Predict?
Of course, the ovulation picture is not complete without confirming successful ovulation. Proov LH and PdG tests make the perfect pair to give you insight into your overall ovulation health.
After getting a positive Proov Predict test, you’ll want to count out 7 days and test with Proov PdG tests on days 7, 8, 9, and 10 past peak fertility. We like to see 3-4 positive PdG tests during the testing window to confirm “successful” ovulation.
Successful ovulation refers to an ovulatory event in which an egg was released and PdG levels remain elevated for long enough post-ovulation to allow for the best possible chance at conception. Without sufficient PdG levels, it can be more difficult to conceive.
What are you waiting for? With Proov Predict and Proov PdG, you can get a complete ovulation picture from the comfort of your home. You can purchase both Proov Predict and Proov PdG tests on our website!
