It is usually the other way around. The physician's test is usually more accurate. It may be that because of the fact that you had voided several times prior to the physician's test that the HCG was diluted out and therefore negative. I would be inclined to believe that you are pregnant given the total of three home positive tests. The blood test should sort this out. If it is negative, then it is unlikely that you are pregnant...
