What does it mean when your period stop and then start back again?

It can happen: Many women have occasional variation of their mucus discharge, some spotting between periods, a heavier or lighter period, a longer or shorter period, an unusual one or even a missed period. Having one or two 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.
