Went to doctor at 9dpo

Went to the doctor for a checkup and I mentioned to them that i might be pregnant and that my expected period isn't til this Saturday I took a urine and of coarse it came back negative(for the third time today) then I got my blood drown and they said it will take 5 days for the results to be in. Do you guys think that bc I am only 9dpo today  and had blood drown that it will come back positive on Monday since there closed on weekends???? Also when should I test again???
