Tested at 10 DPO

My digital clear blue test came back reading not pregnant, but when I opened the test up.. there was 2 lines..

Does this mean I am pregnant ?

I had light pink discharge for 2 days with light cramping at 6 DPO. and I’ve had dull headaches and nausea.

I do not usually spot at all before starting my period…

Im due to start my period in 2 days but have no other signs that it’s coming soon..
