I have been spotting consistent (red to brown) each day for the last two weeks and now i should be on my normal period soon. should i be concerned?

Doctor can evaluate: Many women have occasional variation of their periods, some spotting between periods, a heavier period, a lighter period, or even a missed period. Having one or two of these symptoms doesn’t necessarily mean there is a medical problem, but a call to one’s primary care or Ob-Gyn doctor is a good idea if symptoms are persistent (as in this case), recurring, or worrisome.
