I went through this same problem when I was first pregnant. I even went to the doctor and they were not sure because it was too early in my pregnancy. It is difficult for the pregnancy test to read hormones correctly when it is too early. Your best be is to go to the doctor and get a blood test, they will be able to check for the hormones associated with pregnancy. I know how your mind can play tricks when you think you might be pregnant you keep feeling like you are. Take a big load off of your mind and go in to your doctor. Good Luck.
