The woman was in intensive care in a hospital in the capital, New Delhi, said police in Budaun, Uttar Pradesh state, following Saturday’s attack.
Her brother said the attack took place because the husband wanted to know the baby’s gender. The couple already had five daughters.
“He attacked her with a sickle and ripped her stomach saying that he wanted to check the gender of the unborn child,” said the woman’s brother, Golu Singh.
Police said the baby was stillborn late on Sunday and a man had been remanded into custody.
