I had a negative test: two lines but the test line was much lighter than the control. I've never done an OPK and entered it in the <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a>. It just has a choice between LH surge with two lines and No LH surge with one line. I have a 27-28 day cycle and I'm on CD 11 or so but I didn't start testing the day after my period. My FW just started today. So, QUESTION: What do you count this result as for Glow?
