Woman gives birth after not knowing she was pregnant

PROVO, UT (KTRK) -- Calvin and Brooke Williams walked through the doors at Utah Valley Hospital on Sunday with just two members of their family.

They will be walking out with three later this week.

It all started Sunday morning when Brooke suffered seizures. The couple rushed to the hospital only to find out what triggered them was the biggest surprise of their lives.

"I just honestly stared at her and didn't know," Calvin Williams said.

The first moments of fatherhood were a complete blur for the 27-year-old man, told KSL.

"Just a whirlwind," Williams said. "It's been crazy. I've had every emotion, really."

The new father said when he brought his wife to the hospital after she had several seizures Sunday, doctors were baffled.

"So they did blood work. The guy came back and said ... 'This level is common with someone who is pregnant,'" Williams said.

A sentence the couple thought they would never hear.

"When Brooke was a little girl, she had a brain tumor (and) they told her that she of course wouldn't be able to have kids," Williams said.

In the blink of an eye, that all changed. Their new baby girl is proving doctors wrong.
