As of today I am 10 days late. I have taken tests and they keep coming back negative. I have been extremely tired, feeling nauseous, and no sign of AF. Have any of you ladies with PCOS had false negative pregnancy tests? I read something on the internet that said yes women with PCOS often have false negative tests. What is your experience with this? Am I being overly hopeful? Please help! I have a Dr. Appt Thursday to take a blood test.
