WASHINGTON — Bleeding and in pain, Kyleigh Thurman didn’t know her doomed pregnancy could kill her.

Emergency room doctors at Ascension Seton Williamson in Texas handed her a pamphlet on miscarriage and told her to “let nature take its course” before discharging her without treatment for her ectopic pregnancy.

When the 25-year-old returned three days later, still bleeding, doctors finally agreed to give her an injection intended to end the pregnancy. But it was too late. The fertilized egg growing on Thurman’s fallopian tube would rupture it, destroying part of her reproductive system.
