Hello there.
I can understand your concern.
If both parents are O negative, then the baby must be O negative.
If parents are A and B respectively, then the child can have A, B , AB or O.
If both parents have A, then the child can have A or O.
For more information you can read about it online. There are many articles.
Due to space constraints, i cannot explain in further detail.
Best regards.
