Okay ladies...

I’m now 9 days late for aunt flow. I’ve taken 4 tests. They’ve all been negative. I have what I would say is very very mild symptoms, slight nausea, fatigue. But nothing severe. But usually when I’m about to start af, I get super horrible debilitating cramps, headaches, etc. I don’t have anything like that. What do you guys think is going on???? I’m so confused and don’t know if I should call the doctor or not!
