(CNN) Evelyn Yang, the wife of presidential candidate Andrew Yang, said Saturday that the theme of this year's Women's March -- "Rise and Roar" -- is "very personal" for her after revealing publicly this week that she's a survivor of sexual assault.

Yang told CNN in an interview that aired Thursday that she was sexually assaulted by her OB-GYN when she was pregnant with her and Andrew's first child.

Speaking at the Women's March in New York City, Yang told the crowd her story and admitted it was "terrifying" for her to share on a national stage.

"I had to believe that coming forward would help me reclaim my voice and help others reclaim theirs," Yang said. "Otherwise we would all just be another statistic in the shadows."

Yang said it's a "great, great privilege to have a public voice, and I didn't want to waste it."
