I saw your other question before this one and comment there. Try (and I know this is difficult) to relax, and wait at least two weeks past your missed AF. While many tests claim to be able to test early, there are many factors that influence early hormone levels (late ovulation, late meeting of S and O, late implantation, diluted urine). I usually assume I am pregnant if I'm late, but wait 2-4 weeks past the missed period before taking a test. If I still have a BFN after 4wks past AF, then I consult a doctor/health depo/etc. for further evaluation. Always act like you are pregnant in regards to activities and things you consume until you know for sure.
