My period usually is a regular 28 day cycle. i started my period yesterday and all day it was a pink brown color and by the end of the night it started turning to blood but its mostly the thick brown discharge. its still the same today?

Occasionally happens: 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.
