Five young children were left without their mother when she died just hours after falling ill during a sixth pregnancy, an inquest heard.
Mother-of-five Shellie Westerman contracted a rare infection and doctors were unable to save her.
The 25-year-old, who was ten weeks pregnant, had gone to bed complaining only of a minor headache
which was put down to her pregnancy.
Yet within 12 hours she had died
in hospital from septicaemia after collapsing at home, a coroner in Sheffield was told. After the hearing, her devastated mother Carol Grist said: 'She lived her life for her kids. She was a fantastic mother.'
Miss Westerman, from Barnsley, left Bethany, nine, twins Jordan and Jack, seven, Kai, five and Harley, three, after her death last November.
The children are now being cared for by their father Wayne Green, Miss Westerman's ex-partner, and by her mother.
By the time Mrs Grist arrived at her daughter's home at 8.30am the next day she had collapsed.
'She was limp and her lips were purple. She was going cold,' she said.
An ambulance was called and paramedics worked on Shellie for 40 minutes but could not revive her. She was pronounced dead in hospital later.
Pathologist Dr Kim Suvarna told the inquest there was no evidence of a heart attack or stroke.
She had suffered inflammation of the small blood vessels around her heart and the unborn baby and an infection had entered her blood stream.
The doctor said victims of septicaemia could become seriously ill within minutes or just a few hours. He added: 'A decline in 12 hours would not be unusual.'
