Ms Williams'former partner,Michael Lampe,said he would be"forever haunted by the pain and suffering"he saw her experience on the day of her death on January 1,2016.
"When I look back and read the text messages that she sent that night – asking for help with her pain – it makes me sick,"he said.
"During the time she was pregnant,she went[to hospital] again and again for her nausea. She would come home and tell me how tired she was of just being ignored. She felt like nobody was there listening to her."
Ms Williams'mother,Sharon,said her daughter had felt"invisible to the health system".
"She felt the system didn’t value her as a person and she felt the system didn’t believe her,"she said.
Acting rural group manager for the Riverina at the time,Maria Roche,admitted on Friday that the hospital would not have been meeting the needs of someone who had presented as many times as Ms Williams.
