The answers above are just wrong. The way genetics works, you have 2 copies of the gene that determines blood type. Each copy can be A or B or O. O is the recessive allele. You get one gene from each parent. If you get 2 A's (AA), you are A. If you get 2 B's (BB), you are B. If you get one A and one B you are AB. If you get two O's (OO) you are O. If you get an A and O (AO) you will be A because the A is dominant to the O. Similarly if you get an O and a B (BO) you will be B. So two A parents can have children with type O because the parents can be AO and AO... each can give an O to the kids, ending up with OO children. You can't go the reverse though because if paren'ts are O they must be OO (you can only be O if you are OO). All they can give the kids is O's. (O is actually nothing... no A and no B, which is why it's the universal donor for blood transfusions... there is no antigen for the recipient to react to).
It's easier to explain two + parents having a - child... Since - is recessive to +, you can have + blood type by being either ++ or +-. If the parents are +- and +-, they can each give the child one - ending up with a -- child who has a - blood type.
She can't be type A if you are both O. At least one of the 3 of you would have to be mis-typed.

I've got to say, I'm not very good with genetics, but from what I remember it goes something like this. Everyone has both dominate and recessive alleles and so althought you could be O+, you have a dominate O and a recessive A (maybe) and if your husband was the same, the kid could have inherited the A from you both and made her an A, so even though you both are O's the A could have won out in her. Also, if it's any consilation, there's 5 people in my family and none of us have the same blood type!

I really don't have an explanation but my blood type, my husband, and my two sons are O+. My daughter is O-. Don't know why but it happened. They all three have the same father.

Genetics is confusing- yes someone could have type A- in your family.
It really all about chance, I bet someone from your family and your husbands has type a-
