Edited: I have just started using opks....so bear with me. So I have a 33-35 day cycle. Glow thinks I should have ovulated like 5 days ago but I am just now seeing my lines get darker. These are the darkest my opks have been this month and I started testing around cd 9. Once around noon/1 and again in the evening usually around 8pm. I just learned about this opk tracking app so that is why I only have 2 tests in there, and didn’t think to take photos of the others. I know this first month is trial and error as far as my opks are concerned but how long do you think before I “peak”. These little strips stress me out.
