Short duration of periods. Worry about?

Thank you for your question. Most women experience a variation in their period duration and heaviness off and on during their reproductive years. This is normal. Many life events can affect your hormonal balance which is reflected in your period frequency and duration. Stress, medication, weight gain or loss, eating habits all affect how your ovary responds. As long as your periods are regular and you bleed at least two days you need not worry. But if you are worried or concerned because they have changed abruptly or do not return to normal over 3-6 months you may see a gynaecologist who can examine you and do some tests if necessary. Generally it is better to feel reassured and be checked out than worry by yourself. best wishes
