I'm newly pregnant and bought the weeks estimator tests to try to figure out where I might be in my early pregnancy. Both tests in the box I bought were invalid. They both displayed not pregnant, but when I opened up the test, one strip was clearly positive and the other test had no control line. This happened with both tests! Had I not thought to open it up and check it would have caused a lot of anxiety. These are far too expensive for them to fail! What is being done to prevent this from happening to more women? And how can I be reimbursed?
