Since . Since you've had multiple negative pregnancy tests including a blood test, odds are you are not pregnant. There are many reasons besides pregnancy for a woman to miss her period such as stress, diet, weight loss, excessive exercise, medications, or even a hormone imbalance such as a thyroid disorder or polycystic ovarian syndrome. Also, if you have recently started your period, it's actually normal to have an irregular period for the first 2-3 years. If you are not feeling well or have other concerns about your period, give your doctor a call.
