Im a day late on my period and i started spotting in the afternoon. it was pink, brown and red. and then after an hour, it's completely red when i wipe. but nothing on my liner?

Irregular spotting: Irregular period could be caused by multiple factors including adolescence, stress, diet changes, medications and change in activity or even sleep pattern. If you have been sexually active take a pregnancy test. If negative but spotting persists repeat the test in a week. See your doctor if the spotting continues and negative pregnancy test. Good luck
