My doctor diagnosed me with post pill amenorrhea in Jan after a year of no menses after the birth control pill. My doctor tried chlomid for 3 months which did not work. This month is my first month without the chlomid and just for the heck of it.. thought I would take an ovulation test. To my shock.. it has been coming out positive for the past four days... I'm so confused. My period was actually due about a week ago... could I be ovulating or are the tests just invalid?
