Hi <iam a 26 yr old female,I have been on the 3month injection(contraceptive) for the past 7years and never had my period. Since April 2012 I haven't been back for and injectionmhence in August 2012 I started my menstrual cycle(period) as normal as 5days.For the month of September 2012 I started my period on the 18th September 2012 to this date 01 October 2012,I still bleed cloths,have period pains on and off at times.. In recent days however I did take a pregnancy test and the resuklt was negative.. Is this normal period normal or what could there be a problem ?
