My husband had a vasectomy, but two months later I became pregnant. She called me a traitor, left me for another woman... but I had no idea that

Dr. Salinas greeted me with a soft voice.
“Do you come alone?”
I nodded.
“My husband says this baby is not his.”
The doctor didn't seem surprised.
He didn't judge me either.
He just asked me to lie down.
The cold gel touched my belly, making me tremble slightly.
The screen lit up.
I held my breath.
At first, there was only one blurred shadow.
Then a small spot appeared.
Then that sound filled the room.
A beat.
Strong.
Quick.
I live.
I covered my mouth with my hand and the tears immediately fell down my face.
“Hi, my love,” I whispered.
The Dr. Salinas smiled slightly.
But that smile quickly disappeared.
He moved the probe in another direction.
It slightly frowned.
He expanded the image on the screen.
Then he checked the date of my last menstruation again.
After that, he looked at my medical record once again.
“Mrs. Laura...” Her voice slowed down. “When exactly did you say your husband had had a vasectomy?”
A chill went through my back.
“Two months ago.”
The doctor did not respond immediately.
He pulled the screen.
The heartbeat continued to sound regularly.
But there was something else on the screen.
Something that made the doctor keep the probe completely still, with a totally serious expression.
“What’s wrong?” I tried to join, with my heart beating hard. Is my baby okay? —The
Doctor lowered her voice.
The baby's fine. But I need you to listen to me calmly.
At that very moment, the door of the scanning room was slammed open.
Diego came in without permission.
Paula followed him closely.
“Perfect,” said Diego, in a tone of voice full of sarcasm. Now the doctor can finally tell me exactly how many weeks another man's son is.
Dr. Salinas slowly turned her head to look at him.
He looked at Diego.
Then to Paula.
