There is another potential father.

No, it's not possible at all.
Type O has two recessive alleles: i i, type A has at least one dominate allele, and could be either IA i, or IA IA.
If each parent was type O, ie both i i, there would be no dominate alleles to pass to the child, so the child would automatically be type O, and could not possibly be type A.
Your child has a different father.

Not according to the dominance of your genes. It is possible for a child to have a different blood type than the parents because each trait you have is determined by a pair of chromosomes - 1 from you mother and 1 from your father - with only the dominant one being expressed. So it is possible for someone to be A blood type, but their genes are AO (A being dominant). However, since A is dominant, if one of you had the A gene, then that person would have A as their blood type.
So, in this case, the child had to get the A from someone other than you or this guy.

A blood type of A+ is really two separat things. Your child is type A at the ABO Blood Group and Rhesus + at that trait.
For some one to be blood type A as phenotype, his/her genotype has to be either I(A)I(A) or I(A)i(O). For the ABO blood type, A and B are co-dominant over the O blood type. Means if there is one allele for A or B, the child will be expressed as blood type A or B. If both A and B is in the genotype, the bloody type would AB.
Since the O bloody type is recessive to all others, any individual with bloody type O has to be homozygous i(O)i(O) at the ABO site. If you were i(O)i(O) and so is your partner, then there is absolutely no way your child can be type A. However, I'm assuming you are a true type O. There is a rare case called Bombay genotype, where your blood group is expressed as type O but you have the genotype of i(A)i(O). Because you have i(A) instead of I(A), the phenotype of blood type A is masked. So you are expressed as having type O blood but carrier for type A. In that case, your child can have type A blood. Now that is an extremely rare case, but possible. So don't panic yet, because you could just be that rare case. Go to your doctor and ask for a blood test, mention specificly about Bombay Phenotype considering your child has different bloody group to you and your partner. And good luck with it!
With your Rhesus type, Rhesus positive is completely dominant over the Rhesus negative. So it is possible for your child to be Rhesus positive if you are Rhesus negative and your partner is Rhesus positive.

No. Only a parent with A blood can have a child with A blood. I know this because I am A-, and my son is A+, and my son's dad is O+. If your child has A+ blood, than her father has to have the A type blood because you don't. Hope this helps.

The letter of the alphabet is pretty much a moot point when it comes to blood types. What is important is positive or negative. If your child is a positive during pregnancy and you are a negative then there can be serious complications. Your doctor should be made aware of ALL bloodtypes of ANYONE who might be the child's father.

You better be calling that other potential father...because he's probably the real Dad! Hope you get it all straightened out!

No, our blood type is inherited from one of our parents so your child must have another father.
I'm really sorry and good luck, I hope everything goes ok for you.

oh dear - good luck with this one Asker. As far as my general knowledge takes me, a child has to inherit at least a trait of the monther or father's blood type. But then again, i could be wrong.

No, your child ca not be A+ if both of you are O. your child has a different father.

Blood type is genetically passed from one generation to the next... therefore, the child will receive their blood type from one parent or the other. The following link might help:
