what kind of test?  blue dye tests are notorious for false positive.  blood test is highly accurate.  if you are unsure, repeat with a pink dye test, and if positive, request another blood test.  and do get treated for UTI!

I kNOW that blood test is more accurate than urine test and can detect pregnancy after 24 from implantation while urine test can give false positive results and false positive may be due to:
1-chemical pregnancy
2-missed reaction time(too long to read)
3-chemical interference from FERTILITY drugs having HCG ,medication like trankilizer phenothiazine,contamination with blood or gross amount of protien,
4-evaporation line,you see faint evaporation line as the urine crosses the test in the test area which interpretted as +.
5-medical conditions
6-expired kits.
Ithink scince blood test is negative you are not pregnant, and IF you have urine infection then you may have blood in urine giving false + so i recommened to repeat the blood test again. and see your doctor.
