( lasted ? ) a few seconds."
Other relatives soon came downstairs to Ms Fauvrelle's bedroom where she was "tumbling away from her bed and face first on the floor."
As Melissa approached, she began to see blood.
"Initially Melissa thought there was something wrong with the baby but she soon saw a deep wound by her hand.
"She was screaming, calling for somebody to call the emergency services.
"Other members of the family had come into the room and the scene was highly distressing."
The court heard relatives performed chest compressions while on the phone to an emergency operator in a bid to save Ms Fauvrelle and her unborn baby.
