Blood Type And Parents

The Story

Hello, I recently tested my blood type and it turned out that I am A +, and my parents are 0+, as far as I understood from the Internet, there is no way for two parents with such a blood type to be A +. I began to wonder if these were my real parents, if there was a variant with such blood groups to be like that. How do I know if these are my real parents? Please someone answer me, am I very confused?
