How long after a positive ovulation test does it turn negative?
Disease description:
Recently, my period hasn't arrived, and I've tested positive (strongly positive) on an ovulation test strip. May I ask, how long after a strong positive result on an ovipation test strip does it typically turn negative?

A positive ovulation test result typically indicates that luteinizing hormone (LH) levels in urine have reached their peak, signaling that ovulation is about to occur. This strong positive state usually turns to weak positive or negative within 24 to 48 hours, as ovulation generally happens during this period following the LH surge. However, due to individual differences in physiology and menstrual cycles, the duration of strong positivity may vary—some individuals may take longer for the test line to gradually fade or become negative. When using ovulation test strips, it is recommended to test at the same time each day to minimize variability, and to combine results with other methods such as ultrasound monitoring of follicular development for a more accurate assessment of ovulation timing.
