It : It is very unlikely you are pregnant if multiple tests are negative, but not impossible. Women will sometimes miss periods for a variety of reasons: stress, malnutrition, hormone imbalances, menopause. This can start to happen later in life, especially in women with polycystic ovarian syndrome, now also called metabolic syndrome. You should see your local obgyn as they can do some tests to determine why you are not getting a period, and make sure your next period is not too heavy by inducing a period with some progesterone. It is important to have periods from time to time to protect the lining of the uterus from developing cancer, or the lining can be protected with progesterone.
