Many of us often opt to start using OPK’s (Ovulation Predictor Kits) to get a heads up on when Ovulation may occur. Our LH (Luteinizing Hormone) levels normally begin to rise just hours prior, and can be measured by using OPK’s. Normally the first true positive result – when the Test Line is equal to or Darker than the Control Line, indicates that Ovulation should be taking place anytime within 12-72 hours. But when using these, how will Urine concentration typically effect those results? It’s always recommended to use highly Concentrated (afternoon) Urine between 2-8pm at the same time everyday! Well, I decided to put it to the test. I dipped one OPK test Strip in Concentrated Urine, and then dipped a second one (same brand) around the same time minus an hour and a ½ in diluted Urine. See what happens next!
