Yashoda Gurung's family survived 20 years in a refugee camp after fleeing war-torn Bhutan.
But her mother died months after arriving in the U.S. in 2009 and seeking a legal abortion in Philadelphia.
Karnamaya Mongar's overdose death is the subject of one of eight murder counts in the ongoing trial of Dr. Kermit Gosnell.
The 72-year-old Gosnell is also charged with killing seven babies born alive.
Through a translator, Gurung testified Tuesday about the labor-inducing drugs and painkillers her mother was given as she waited hours for Gosnell to arrive for the procedure.
She said her mother was later taken to a hospital, but only after firefighters struggled to cut bolts off an emergency door. Mongar died the next day.
The family, which lives in Virginia, has a wrongful-death lawsuit pending against Gosnell.
Gurung, 26, testified that she wanted her mother to have the baby but that Mongar insisted that another baby would be too much after years spent living in a Nepal refugee camp, the Philadelphia Inquirer reported Tuesday.
Gurung said that 16 weeks into her mother's pregnancy, she traveled with her, as well as with Mongar's brother, to Gosnell's clinic on Nov. 19, 2009, according to the newspaper.
Gurung reportedly told the jury that her mother slipped into a coma following the abortion and then died the next day in the Hospital of the University of Pennsylvania. Prosecutors claim Mongar died when the doctor's untrained staff gave her too much Demerol to anesthetize her, the newspaper reported.
