This morning I took a clear blue digital test and it said Not Pregnant. But I still had a feeling so I went and bought a first response test, done it and BFP within he three minutes. The line is faint but very obvious, no mistaking its there. What do you think? How could one test say bfn and another bfp a few hours apart. I am on day 31 of a 29 to 33 day cycle!
