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, the 24-year-old 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 41-year-old mother was later taken to a hospital, but only after firefighters struggled to cut bolts off a side door of the clinic. Mongar died the next day.
The family, which lives in Virginia, has a wrongful-death lawsuit pending against Gosnell.
