Why am I having Pregnancy symptoms and negative pregnancy test results? Am I testing to early?

The darkening of the areolas usually do not start until way later in your pregnancy (like, the 6th month), but every woman is different. I would suspect the back pains and dull cramping to be good signs of early pregnancy, but those could also mean you are getting ready for your period. Wait about another week, and take another test, I think you're testing too early. There is a very good chance that you have conceived again, because women are usually very fertile after having a baby or miscarrying. Good luck, let me know!
