"Well, actually it was an accident," she told King at the 2017 TED Talks conference in Vancouver. "I was on vacation just taking some time for myself and I have this thing where I’ve been checking my status and taking pictures every week to see how far along I’m going," Williams explained. "I didn’t tell a lot of people to be quite honest and I’d been saving it," she continued. "Every week I just take a picture and save it and I’ve been so good about it and this was the one time I slipped, but it’s okay." She added, "On social media, you press the wrong button and… 30 minutes later I missed four calls and I’m like, ‘That’s weird.’ But it was a good moment. I was only going to wait five or six more days [to tell people]."
