I had my period on the 17th then stopped in the 20th and this morning i started to spotting so i took a pregnancy test and it came back negative, later on in the afternoon it became more then just spotting?

Tests are accurate: Many women have occasional variation of their mucus discharge, some spotting between periods, a heavier period, a lighter period, a longer or shorter period, or even a missed period. Having one of these symptoms doesn’t necessarily mean there is a medical problem, but a visit to one’s primary care or Ob-Gyn doctor is a good idea if symptoms are persistent, recurring, or worrisome.
