SALT LAKE CITY (AP) — A not-so-expectant Utah mother is still a little surprised by her newborn daughter's arrival.

KSL-TV reports Angie Hernandez thought she had an upset stomach when she went home from work May 25. She says she got in the bath hoping that would calm her and that's where she gave birth. Her oldest son was outside the bathroom door and she told him to call her husband and boss.

Both mom and baby girl were checked over at the hospital. Hernandez says her 20-month-old daughter was born naturally, and that this most recent birth was not painful. Her period was normal throughout and she wore her same-size pants. Relatives suspected a belated April Fool's joke or that Hernandez's 16-year-old son had a baby that the family agreed to raise.
