How do I read an ovulation test correctly? OB/GYN in Seoul, Korea
The short answer
Compare the test line with the control line, not with yesterday's test. It is positive only when the test line is as dark as, or darker than, the control line. A positive result means ovulation is likely within about 24–36 hours. If unsure, photograph the strips and bring them to the clinic.
Start testing a day or two before your expected ovulation. See ovulation tracking.
