“The baby is AB positive, Mrs. Davis,” the specialist said, looking at me with a pity that made my stomach turn. “And your husband is type O. Scientifically, he cannot be the father.” I stood there, my hand gripping my seven-month pregnant belly, because my brain genuinely stopped working for a second. I had never cheated. Not once in our 11 years together.

Mark was the only man I had ever loved. We met in college, got married in a small backyard ceremony, and spent a decade building a quiet life in Fort Wayne. We saved our money, drove used cars, and planted tomatoes in our small backyard. This pregnancy was our miracle. We had tried for five years, and when the test finally turned positive, we cried in each other’s arms on the kitchen floor.

But now, sitting in this cold clinic room, the world felt like it was spinning out of control. The specialist, Dr. Vance, was adjusting his glasses and looking at a printout of my blood work. He had run $8,400 in advanced prenatal genetic testing because of a minor scare during my last ultrasound. The baby was perfectly healthy, but the blood markers didn’t make sense.

“Are you absolutely certain about your husband’s blood type, Clara?” Dr. Vance asked. His voice was too gentle, the way people talk to you when they are about to deliver bad news.

“Yes,” I whispered. My throat felt so dry I could barely swallow. “Mark is type O. He gives blood at the red cross every spring. He has the little card in his wallet. And I am type A. I’ve always been type A.”

Dr. Vance sighed, leaning back in his leather chair. “An O parent and an A parent can only have a child who is type A or type O. It is a biological impossibility for you to have an AB positive baby together.

The baby must have inherited the B allele from the biological father. I’m sorry, Clara.”

I didn’t scream. I didn’t cry. I just sat there while my jaw locked up and my hands started to tremble. The silence in the room felt heavy and suffocating. I wanted to tell him he was wrong. I wanted to shake him and tell him that Mark was the only man who had ever touched me. But the numbers on the page didn’t care about my loyalty.

I walked out of the clinic and got into my Buick. The steering wheel felt freezing under my hands. I sat in the parking lot for fifteen minutes, just staring at the gray brick wall of the medical center. My mind was racing, trying to find a loophole, a mistake, anything. I was so desperate that I picked up my phone and called my mother.

My mother, Evelyn, had raised me in a strict, loving household in Toledo. She was a retired school secretary, a woman who kept her kitchen spotless and her bible on the nightstand. She was my rock. When she answered, I broke down.
