Bulimia a cause of a false negative?

Try taking a better test like ept which reads pregnant/not pregnant. Sometimes the dollar store test's don't pick up small traces of HCG levels and you can get a false negative. In the mean time, please take care of yourself and the ED incase you are pregnant. I would also make an appt with your doctor to confirm and make sure there isn't another underlying issue as to why your not getting your period now. Best of luck!
