I took 3 preg. test and they be posive i go to the doctor for my blood check and it be denial?

The only piece ( except if you are taking fertility medications) that will give a positive HPT result is the hormone HCG. It depends on how long between the urine test and when you had the blood try-out. if you began bleeding within between you could have have an early miscarriage ( up to 50% of adjectives conceptions end within undiagnosed miscarriages that people of late think are cumbersome or late period.) You also could have have a hormone imbalance. Would have need of alittle more info though. If you are still wondering , ask the doctor who ran your blood testing.
odd it could be a hormonal inconsistency changing the results so ego keep an eye on it .. are you on meds ? meds can translation the outcome
