My 74-year-old father invited me to dinner and offered me a drink. I accepted, but the next morning I woke up feeling terribly ill and went to the hospital. When the doctor saw my blood test results, his expression suddenly changed. He asked, “Have you suspected lately that you might be pregnant?”

She nodded, but her eyes seemed unusually sad.

After dinner, he insisted that we take a picture together.

—Someday you'll understand why tonight is so important.

I thought I just missed Mom.

But when I was about to leave, he grabbed my hand.

—Sarah, if something unexpected happens tomorrow, please don't panic before you know the truth.

I stared at him.

—What are you talking about?

He shook his head.

—You're welcome. Forget what I said.

That night I woke up with terrible nausea.

My stomach was upset, my head was spinning, and I was so weak I could barely stand up.

I felt even worse in the morning. I called my doctor, who advised me to get a check-up.

At the hospital, a nurse drew several blood samples from me. About an hour later, I was called into Dr. Wilson's office.

I was examining my results with a strange expression.

—Sarah, can I ask you a personal question?

-Of course.
