Why Do I Have Irregular Periods?

Menstrual cycles can be anywhere between 24 and 34 days apart, the average being 28 days apart. Each month your period may vary by an entire week; this is normal. If your cycle becomes more irregular than that, it could indicate a hormonal change is occurring in your body.
  1. Keep A Calendar

    • Keep a calendar of your periods so that you know what is normal for your menstrual cycle. Every woman's cycle is different, and just as long as you are consistent with what is normal for you, then you are considered as having regular periods. If something changes drastically, go see a doctor.

    Hormones
