Even though periods are a normal and natural part of a woman's life, many women perceive it to be an intrusion or a disturbance in their daily lives. It's possible that your periods just make you feel run down or fatigued. However, if you were experiencing other symptoms such as pain when you go through your period, or if it was affecting your work or social life, then you should see your doctor. In general, having regular periods is a sign that your body is still producing estrogen and therefore still functioning properly. If your periods are irregular or if you don't have them at all, this could mean you have any number of health problems. You should never stop having periods even if you think that something has caused this to happen to you. If you aren't producing any estrogen, your periods will stop altogether within a few years. Starting around age 30 your bodies ability to produce estrogen decreases every time you give birth. With each child, your risk of developing breast cancer increases. If you're a man with regular periods, this means that you are still producing testosterone which is good news for you if you suffer from depression or anxiety. However, if you aren't producing enough estrogen or enough testosterone, you may experience some health issues related to hormone imbalance. Examples include: excessive hair growth (on face or elsewhere on body), changes in skin or mood, etc.
