The <a href="https://play.google.com/store/apps/details?id=com.glow.android">GLOW app</a> said I was due to Ovulate about a week or so ago. I took tests every day and the lines were close but it never got quite as dark as the control and it definitely never got darker. I stopped testing for a few days but Ovia another app I use said I was due to Ovulate this week so I tested yesterday (that's the whiter one) and today ( the pinker one) I feel like maybe GLOW is wrong and maybe I'm having a surge. My husband is really sick and doesn't think he can perform. I'm trying to not be upset but I have never had such a dark test line since starting to test. I'm feeling like this is it. No BD tonight and I'm not sure I'll see this again.
