I’m so confused

Jo

Hey ladies. My period as of today is 9 days late. Tomorrow being 10... I’ve had non of my usual symptoms of AF. My mood hasn’t changed much, my boobs have been sore but not awful. I’ve had three negative tests. One on my fourth day late mid day, one yesterday mid day and one this morning with first mornings urine. Has anyone been through this and if so what was the outcome? Thanks in advance.
