I need your help 😞😞😞 please

Ok please help me understand why this is happening to me...

Starting 7DPO I started testing for pregnancy up to today which is 10DPO

as you see its looks like a VVFL all days prior but then this morning I tested again and it’s gone😫😫😫

Did I miss something was I pregnant and then lost it or was it’s false positive from the beginning omg whyyyyy

Any opinions helps
