Woah baby! Woman who didn’t know she was pregnant gives birth after a run

Most people probably experience a bit of pain after finishing a 9-mile run but not the kind that Trish Staine found herself in on Sunday.

The Minnesota woman was training for a half-marathon when she was hit with excruciating back pain.

"I was yelling and screaming — I thought I was dying," Staine said.

The next day she was holding onto her brand new baby girl.

Instead of a pinched nerve, kidney stones or a burst appendix – Staine was pregnant.

"And I’m, like, looking around, like, no, I don’t believe it," Staine told TODAY on Thursday.

She said that she hadn’t missed any periods, never felt any fetal movements and didn’t have a "baby belly".

Her husband John even had a vasectomy. But when John walked into the hospital, doctors congratulated him on his "brand-new baby girl," he said. 

"I definitely thought I was done having kids," Staine joked.

The couple already have a daughter, 7, and a son, 11. She's also stepmother to John's three boys, ages 17, 19 and 20. The pair also have two foster children.

Their new daughter named Mira – short for Miracle – was born at 3:25 p.m. Monday weighing 6 pounds, 6 ounces, and was 18.9 inches long.

They may be shocked but Staine said she and her husband have a good sense of humor about the situation.

"He's still in shock. Everybody is teasing him," she said.
