There are two different lines that can show up on your Modern Fertility Ovulation Test:
- The control line should show up every time you test — this line tells you that the test is working as expected and that the test is not faulty.
- The test line will appear (to the left of the control line) when the concentration of LH in your urine is above zero.
- If you don't see a test line appear, it means your LH concentration is at its lowest levels.
- If you do see a test line, you'll use it to figure out your actual LH concentration by scanning it into the Modern Fertility app, or comparing your test line to the included color chart.
