Hello Thank you for your query. In the face of negative pregnancy tests, you are most probably not pregnant. Absence of periods could be due to stress, anxiety, fluctuations in weight, emotional upheavals, hormone disturbances, thyroid disorder, polycystic ovaries, certain drugs and medications etc. Pale face suggests anemia, which is also a cause of irregular cycles. Rarely, you could be having a very early pregnancy or an ectopic pregnancy, which might not show up easily or soon on home pregnancy kits. Please visit your gynecologist for specific diagnosis, and reason as well as treatment of anemia. Take care.
