Editing the glow app to read accurate OPK results

Carly

Hey!

Needing some help to understand the app or possibly be pointed in the right direction. The <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> forecasted today would be my first high fertile day however the OPK I did read negative. How to I amend the app so it correctly reflects the true tests?
