Maybe or maybe wait: Maybe wait another month. 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 or two of these symptoms doesn’t necessarily mean there is a medical problem, but can visit one’s primary care or Ob-Gyn doctor if symptoms are persistent, recurring or worrisome.
