For the past few months, about 10 -14 days before my period is due, i have light bleeding (heavier than spotting, but not heavy like a period) it starts out brown, but then becomes bright red. i don't have any unusual pain.

Can give Dr. a call: Many women have occasional variation of their mucus discharge, some spotting between periods, a heavier or a lighter period, or even a missed period. Having one 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. Be sure annual preventive care is up to date.
