If your period comes early once in a while, it is likely normal and not a cause for concern.
Menstruation might start early because of a change in your lifestyle, intense physical exercise, illness, or stress. However, sometimes it happens with no reason, and this is still not necessarily abnormal. So, if you get your period a week early, try not to worry. If your period is consistently irregular, you can let your health care provider know to rule out any problems.
Many people have irregular periods occasionally; others have them throughout their lives.
Some possible causes of getting your period early:
- Hormonal imbalance
- Medical conditions
- Taking certain medications
- Poor nutrition
- Sudden weight gain or loss
Your birth control method can also affect your cycle. An emergency contraceptive pill can cause an early period. If you skip a few combined oral contraceptive pills, your hormone levels may drop, and bleeding may start before it’s due. If you have recently had an intrauterine device inserted, your body may react to it by bleeding.
To avoid unpleasant surprises with your period coming early, it might be a good idea to have period products on hand, even if you’re not expecting your period. If you’re getting your period early for a prolonged period of time, make sure to ask your health care provider about it.
