My period was late (only by about 2 days) but it had been odd, only bled normally for a day and now have barely even drops throughout the day (not even enough to fill a panty liner), what could be causing that?

It happens sometimes: 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 a visit to one’s primary care or Ob-Gyn doctor is a good idea if symptoms are persistent, recurring, or worrisome.
