I am on birth control and i got my period early and its bright red. should i be worried?

Probably normal: As long as this is a transient, as opposed to recurrent, occurrence (more than 5 cycles). This can especially become an issue with ocp (oral contraceptive pill) transitioning. If symptoms persist and/or worsen, it would be wise to undergo a work up. Depending on your age, history and stage of reproductive life, the differential diagnosis is vast.
