No, the ovulation self-test is not a contraceptive method and should not be used to prevent pregnancy.

First-morning urine is highly concentrated, which can lead to false-positive results. It is recommended to collect urine at the same time each day, avoiding the first-morning sample.

Alcohol does not affect the result, but it is recommended to consult a doctor if undergoing hormone treatment. Recent oral contraceptive use, breastfeeding, or pregnancy can influence test outcomes.

A positive result occurs when both the Control (C) and Test (T) lines are visible, and the T line intensity is equal to or greater than the C line, indicating ovulation will occur within 24 to 36 hours.
