Early period: possible causes and risks

Getting your period early is unpleasant. Unfortunately, there are many factors that can cause early menstruation. Today we’ll tell you all about them and teach you to control your body mechanisms a little bit.

Period a week early: is there anything to worry about?

If your period comes early once in a while, it is a normal occurrence and not a cause for concern.

Menstruation can start before its due time because of a change in your lifestyle, intense physical exercise, illnesses, or stress. However, sometimes it happens without a reason, and this is still not necessarily abnormal.

Detect early periods better!

Use Flo to record your periods. This will help indicate whether it is early or not and may show patterns that will help you understand your body.

Reasons for early periods

Many women have irregular periods occasionally; others have them throughout their lives.
Reasons for an early period include: 

  • hormonal imbalance 
  • illness 
  • taking certain medications 
  • menopause
  • over-exercising
  • poor nutrition
  • stress
  • sudden weight gain or loss 
  • travel

Your birth control method can also affect your cycle: an emergency contraception pill can cause an early period. If you skip a few COC pills, hormone levels drop and bleeding may start before its due time. If you have recently had an intrauterine device installed, your body may react to it by bleeding.

To avoid unpleasant surprises with your period coming early, you should always have feminine hygiene products on hand.

  • Such an intuitive app! Hannah Malone
    I've tried several period tracker apps on the market and nothing is as good as Flo. It's accurate, detailed providing you with an abundance of parameters to log, and they even provide useful articles and surveys to help you better understand the complex nature of the female body.
