Ovulation Kits

Start testing several days before you expect to ovulate. For most cycles, once-daily testing is enough. Test in the afternoon or early evening, roughly between 10 a.m. and 8 p.m. LH is made in the morning and shows up in urine later in the day, so afternoon samples are more likely to catch the surge. Avoid first-morning urine, and limit fluids for about 2 hours before testing so your urine is not diluted.

Yes. Testing twice a day, once in the morning and once in the evening, helps you catch a short LH surge when hormone levels change quickly. This lowers the chance of missing your fertile window.

Test on consecutive days until you detect your LH surge. Most people test for 5 to 10 days per cycle, starting a few days before expected ovulation based on cycle length. Testing across several cycles shows your individual pattern and improves conception timing.

Pregmate ovulation tests measure luteinizing hormone (LH) in urine. An LH surge means ovulation is likely within 24 to 36 hours.

The strip reacts to LH in your urine. As LH rises, the test line gets darker. Reading that change over several days shows when LH reaches its peak.

A result is positive when the test line is as dark as or darker than the control line. This test-to-control (T/C) ratio is the standard way to read an LH surge, and it is the same signal the Pregmate app uses when you scan a strip. Unlike a pregnancy test, a faint line on an ovulation test is negative.

Read the result at 5 minutes, as stated in the instructions. Do not read it after 10 minutes, because the lines can change and give a misleading result.

A faint test line means LH is present but has not reached surge levels yet. Only a test line as dark as or darker than the control line counts as a positive surge. This is the opposite of a pregnancy test, where any visible test line can indicate pregnancy.

Yes. In laboratory studies, Pregmate ovulation strips detect the LH surge with 99% accuracy when used as directed. LH rises 24 to 36 hours before ovulation, so these strips are a reliable way to identify your fertile window. Accuracy here means LH detection, not confirmation that ovulation has occurred.

No. Ovulation tests detect the LH surge that comes before ovulation. They predict when ovulation is likely but do not confirm that an egg was released. To confirm ovulation, pair LH testing with basal body temperature (BBT) tracking. BBT rises after ovulation and stays elevated if conception occurs.
