I've tried cheap strip, cassette, clear blue and then finally frer and all have come back with faint lines, I done a cb digital 2 days ago (the same day i got positive on frer) and was negative. I'm due af today. if I tested Monday would be 3 days late obviously if af doesn't show. would a digital say pregnant? I recently had a miscarriage and I've previously had a chemical so don't want to contact doctor untill I get a positive on digital. Please share your experiences
