So i started bleeding a week early only last a few day which was on the 31 of may and my period isn't due till the 5 of june it was very lite pinky to?

Early period.: Some reasons for early periods include fatigue, anxiety, stress, marked weight loss or gain, significantly poor nutrition or intensive exercise.

Vaginal bleeding: Bleeding between periods has lots of possible causes. Not sure what you mean by "pinkish", but if the blood is mixed with vaginal discharge, then infection might be likely -- and STDs are among the most common infections causing vaginal bleeding. Any abnormal or unexplained vaginal bleeding and/or vaginal discharge should be professionally evaluated. See a doctor ASAP. Good luck!
