    What Causes Missed Periods?

    Did you miss your period this month? Pregnancy is the most likely cause. But there are many others.

    It could be due to stress, weight changes, and too much exercise, says WebMD guest expert Hyacinth Nicole Brown, MD. Missed periods can also be signs of medical problems that need treatment. They include hormone problems, eating disorders, and some diseases.

    Irregular periods can affect your chances of getting pregnant. So if you have fewer than nine periods every 12 months, or your periods have stopped completely for three months, see a doctor. You'll need an exam and tests to see what's going on.

    Have you had irregular periods? What do you think causes them?
