SAN FRANCISCO -- A 400-pound California woman went to a hospital complaining about a stomachache and got the shock of her life when doctors said she was very pregnant.

Only 48 hours later, April Barnum delivered a healthy baby boy.

The Orange County Register reported that doctors saw the baby after an X-ray and sent Barnum to the University of California-Irvine Medical Center. The baby's lungs were fully developed, the heartbeat was strong and no defects were detected. Two days later, Walter Scott Edwards III was delivered by Caesarean section, weighing in at 7 pounds and 7 ounces.

Barnum and her fiance, Walter Scott Edwards II, said they had no hopes of having any children and had instead spent money on adopting four dogs.

Edwards said he is lucky to have relatives who have come forward bringing the necessary items.

According to doctors, Barnum's weight was responsible for her not realizing she was pregnant. Since her monthly cycle also stopped a few years ago, because of her obesity, she did not have any other way to detect it.
