I've had my period the last week in august and the last 3 days now so only a week apart .. what does this mean?

Need more info: Are you on contraception? Which ? skip a dose? What medications are you taking? under a lot of stress right now? Have you been traveling , changing time zones or not sleeping enough? Excessive exercise? These are things that can throw our cycle off and cause mid-cycle bleeding . not all bleeding is your period. If you're at risk, get urine preg test and screened for STDs. Can cause bleeding too
