it's not very likely, blood tests are very accurate and HCG (pregnancy hormone) shows in the blood before in the urine. HPT's are not as accurate and sometimes can provide a false positive result, though it's not all that often. Sometimes if you look at the test after the time allowed in the instructions you will see a false positive line. ~pawsalmighty
No.

yes
No, it is not possible.
A positive, O positive, A negative, or O negative; all are possible
Yes, it is possible for a mother with A positive blood and a father with O positive blood to have a baby with A negative blood. The baby would inherit one A allele from the mother and one O allele from the father, resulting in A negative blood type.
Can o negative blood boy pregnant o positive girl

it is possible but the child can be a positive
No, it is not possible for parents with blood types B negative and O positive to have a child with AB positive blood type. The AB blood type requires an A allele from one parent and a B allele from the other, which is not possible in this case.
Yes. It is possible.
Yes, it is possible for a child to have a negative blood type if both parents are carriers of the Rh negative gene, even if one parent is O positive and the other is A positive. Blood type inheritance is determined by a combination of both parents' blood types and Rh factors.
