Carla Murtagh, from Shard End, Birmingham, had booked an abortion for October 28 but later changed her mind and decided to keep the baby.
Nine days later the 34-year-old, who had a history of depression, was found hanged by her distraught husband Matthew who went upstairs to look for her after he thought she was ‘acting quiet’.
Mrs Murtagh was rushed to Heartlands Hospital by paramedics who failed resuscitate her, Birmingham Coroner’s Court was told.
Doctors then performed an emergency caesarean on Mrs Murtagh, who was 25 weeks pregnant at the time, but the baby was stillborn.
A short time later she was pronounced dead by medics.
On the day of her death husband Mr Murtagh described how she had woken up in a ‘bad mood’, but had otherwise seemed fine.
Mrs Murtagh had started to cook a meal as the family was celebrating a birthday that day.
He had left the house with two of their children to buy a birthday cake from the supermarket.
When they returned, he said Mrs Murtagh had gone upstairs and was ‘acting quiet’.
‘She went upstairs and told me that she wanted to be left alone,’ he said.
‘I went downstairs to dish up the dinner and went up to get her.’ He found his wife hanged in the bedroom and called for help.
He attempted CPR as paramedics arrived, and Mrs Murtagh was taken by ambulance to Heartlands Hospital.
The inquest heard how she and Mr Murtagh already had seven children, aged between 15 years and 14 months.
