When Sara Laub’s period was late, the New York City resident shrugged it off. She’d used an intrauterine device, or IUD, for three years and knew her odds of getting pregnant were extremely slim. But after 10 days had passed, Laub, 28, took a home test in early July and got unwelcome news: She was pregnant.
Laub went to a Planned Parenthood clinic because she knew someone could see her immediately there. An ultrasound found no sign of a developing embryo in her uterus. That pointed to the possibility that Laub might have an ectopic pregnancy, in which a fertilized egg implants somewhere outside the uterus, usually in a fallopian tube.
