First time attempting OPK. I’ve been testing since April 27, CD4 according to glow. I feel like all my test strips have been pretty dark and all look pretty similar. I’ve gotten a lot of “almost there” when I scan into glow. Around midnight 12:00am this morning 05/06/18, glow logged my strip as positive. I rescanned a few times to see if it’ll change because sometimes the results do change, but this stayed positive with every scan. However, I’m still unsure and feel like the test strip is still very slightly lighter than control line. What do you ladies think? TIA!
