If you took the tests the right way and followed the directions, the positive tests are a good indicator that you ARE pregnant. It's important to read them right away. If you let them sit, they will get a second line that is not pregnant but an evaporation line. How did you use the tests? Are you late for your period? Any other symptoms?
Looking back at all my personal strugglings I do want to believe everyone on this path gets her little one. This time is not the exception. If you did follow the instruction right, and the home cheapie showed BFP, then congratulations! To make sure you could also use some other brends. to see if their results coinside. For more accurate answer - blood test. trully hope this is your rainbow!
