To all the ladies worrying about late periods try taking large doses of vitamin C . Vitamin C jump starts your period by your body producing the hormone that brings on your period. Use vitamin C WITHOUT rose hips that defeats the purpose. Take 1-2, 500 mg tablets of vitamin C a hour for 1-3 days and you should start to bleed . May work up to 3-4 weeks after a missed or late period . (Also may not work for everyone it just worked for me...I was 3 weeks late and started bleeding 16 tablets later )
