In his decision, the pope said he understands that many women feel that they have no choice.
"I have met so many women who bear in their heart the scar of this agonizing and painful decision," he wrote.
The Vatican did, however, make it clear that this does not mean that the church condones abortion.
Pope Francis made that clear during his conversation this week with Americans in three different cities. He was listening to the story of Rosemary, a single mother living in Los Angeles.
"You are a courageous woman because you brought your daughters into the world," he said. "You could have killed them in your womb, but you respected life."
He told Rosemary to walk with her head held high.
