Holly Alvarado realized she might be pregnant while standing in the middle of a Walmart near Grand Forks Air Force Base, where she was stationed in 2009. Alvarado, then 22, was struggling to afford the supplies, like socks, underwear, and boots, she would need for at least six months in the Middle East. She had emptied her apartment of most belongings except for the sleeping bag she crawled into at night and crammed the rest in a storage unit, an expense that would grow over time. Alvarado had two weeks left in North Dakota before pre-deployment training began in Texas. From there, she would go on to serve her country. Alvarado knew she wanted an abortion almost as soon as she experienced her first wave of nausea in the Walmart. But Tricare, the military’s health-insurance program, would not cover the procedure.
