Sounds like you aren't pregnant or you don't have enough hormones built up to trigger a positive pregnancy test. Take another test in a few days and always, always use FIRST morning urine. It contains a higher concentration of HCG.

sometimes there can be implation bleeding which is where the embryo attatches itself to your wall in your uteris. this is usually not a heavy nor dark blood, many say it is like rad or pink and it only last about a day or so if you have had a negative test i would agree with mabel and wait another week then test again some wemon dont build up the hcg hormone as much as other so...id wait another week and do it again.
