According to Glow I am a day late, according to Maybe Baby I'm four days late...I took two pregnancy tests... Not only were they inconclusive but one both circles turned completely blue, no lines appeared but they were fully blue... The other one nothing happened at all. Not even the control showed up. Did I just get a faulty batch? Has this happened to anyone else???
