Twenty-Three Years of Being Single, Yet Pregnant

Recently, I've been feeling unwell. Taking advantage of the weekend, I decided to go to the hospital for a check-up.

The doctor glanced at my report and asked why my boyfriend wasn't with me.

"I don't have a boyfriend," I replied.

He gave me a puzzled look and double-checked the report.

"You're one month pregnant," he said.

I've been single for 23 years and have never had a boyfriend. So where did this baby come from?
