9 DPO Testing

Has anyone ever gotten a negative at 9 DPO and gone on to get a positive? I have NEVER tested before my period was at least 3 days late, but this would be my 4th pregnancy and I’ve gotten all of my tell tale early symptoms and then some. I was wondering if maybe I had ovulated earlier than expected so I took a n early response test today. I took it late morning soon after a large iced chai so that may not have helped, but it was pretty stark negative. Anyone ever had a very negative test at 9 DPO and had a positive later on??
