Test date for first cycle charting


This is my first cycle charting on Fertility Friend. Why is my proposed test date so far away?

The reason the test date seems far away is because we don't have statistical data from you showing a usual luteal phase length. Without this information, we can't know when you are really "late." In this case, we recommend waiting to test until 16 to 18 days past ovulation to avoid wasting tests and the disappointment of seeing negative test results or the confusion of not knowing if a test result is a false-negative or not.

If you know your usual luteal phase length, you can take a test when you are one or two days past that time and you are likely to get reliable results.
