My period is usually always on time the first of every month this month it was 5 days early first it was pink,brown and it was red and light help me. ?

Likely nothing wrong: It is very common to have an irregular cycle every so often, especially if not on birth control pills. Stress, sleep change, exercise/diet change, etc can all contribute. Keep a calendar of the next few cycles and if they continue to be irregular, see your doctor for evaluation.

Probably ok: One unusual period is not generally a concern unless repeated.
