What is an ovulation test?
An ovulation test is done by analyzing the levels of luteinizing hormone in the urine with a test strip. These tests are also known as LH tests or OPKs (Ovulation Prediction Kits).

You can buy ovulation test strips in our webshop or at your local pharmacy.
When to take an ovulation test
An increase in LH is usually found within 24-48 hours before ovulation, so it’s best to test in the days before your expected ovulation.
The Natural Cycles app lets you know when the best time to test is by showing an ovulation test symbol (see below) in the predictions on the days you should take an ovulation test. You can see the predictions in the Calendar and Today views. These suggestions are optimized so that you have to take as few tests as possible without missing your peak. You can, however, always test more (or less) than what’s suggested.

How to take a Natural Cycles branded ovulation test
If you use ovulation tests from a brand other than Natural Cycles, always follow the directions of the manufacturer.
1. Collect a urine sample in a clean, dry plastic or glass container.
2. Remove the test strip from the sealed pouch.
3. Immerse the strip into the urine with the arrow pointing towards the urine. Take the strip out after three seconds and lay the strip flat on a clean, dry, non-absorbent surface (such as a closed toilet lid).
IMPORTANT: Do not allow the urine level to exceed the MAX (marker line); otherwise, the test will not perform correctly.
4. Read the results immediately once five minutes have passed. Do not wait to read the results after longer than five minutes.
You can take ovulation tests as many times a day as you wish. If you see a second colored band, but it's not strong enough to be considered positive, it can be a good indication to test a few hours later.
To ensure that you do not miss your LH peak, it is recommended that you limit your fluid intake for a few hours before testing (to prevent the LH from diluting).
