A woman in Attleboro takes an at-home test and finds out she’s pregnant. She looks up nearby reproductive health clinics and finds one: Four Women Health Services, which has also been providing abortions for decades. She sends a request through an online chat on Four Women’s website to set up an ultrasound appointment.

Less than half an hour later, she receives a call to schedule an appointment and books one.

But the person who just called her doesn’t work for Four Women. They called to book her an appointment at the center across the street: Attleboro Women’s Health Center, or Abundant Hope.

That’s what allegedly happened last October. Four Women is now suing in federal court, alleging that at least four potential patients apparently had their messages intercepted by Attleboro Women’s Health Center — an entity that is not a licensed health care facility and does not provide abortions.
