I am on birth control but the past few months I have been starting my period a week early and it is not that heavy of a flow and only lasting two days which isn't normal for me. I have been feeling very tired and have been having horrible headaches. This month I have gotten fatigued, tired, and sick to my stomach. But I still started my period a week early and now I have been bleeding for two weeks. Does this mean something is wrong?
Your period will not go back to its original schedule. It was only a week early once and it is now following the new schedule. What is important is the number of days that the cycle is long, not the actual dates.
It sounds like you might have some hormonal or health issues. The best will be to see your doctor.
