This video shows her hobbling around the maternity ward in the final hours before her death.
She is seen walking around, aided by an unknown man, and falling to the floor doubled over in pain.
At one point, she leans against a wall and looks almost ready to collapse.
She is also seen kneeling on the floor in distress as others, who appear to be her family, crowd around her.
The woman, who was reportedly 41 weeks pregnant, was unable to stand unaided and was visibly upset and in pain.
Doctors at the No 1 Hospital in the city of Yulin in Shaanxi Province, northern China, examined her and determined that she needed a caesarean as she was not able to give birth naturally because the baby’s head was too big.
But her family insisted on a natural birth and refused her the right to undergo the procedure.
Under Chinese law, family must give their permission for a woman to have a C-section.
The woman fell to her death from the window after repeatedly trying to leave the medical centre.
Her unborn foetus also died in the incident.
The woman’s medical notes read: "The pregnant woman twice walked out of the ward to tell her family that she wanted a caesarean because she could no longer bear the pain, but the family continued to insist on a natural delivery."
Police told local media that the woman’s death was being treated as a suicide.
Her death has sparked protests online with other women calling for greater reproductive rights.
One internet user commented: "Besides the pregnant woman, nobody else should have had a say."
Another noted: "A married woman isn’t a tool for producing babies, how can people still be so ignorant these days!"
