Just because she’s engaged to a tech giant, that doesn’t mean Serena Williams has mastered technology. 
 
 The pregnant tennis champ opened up about her pregnancy to Gayle King at Tuesday’s 2017 Ted Talks conference held inside the Vancouver Convention Centre and revealed that her baby bump Snapchat was sent out to the world by accident. 
 
 “Well, actually it was an accident. 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, 35, said. “I didn’t tell a lot of people to be quite honest and I’d been saving it. On social media, you press the wrong button and… Thirty 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 share].” 
 
 But the slip-up doesn’t have her stressing about future social media posts. “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 said. 
 
 One week ago, the mother-to-be captioned a mirror selfie with her baby bump clearly visible underneath a custom yellow La Blanca Anniversary suit. “20 weeks,” she announced. 
 
 Later that same day, Williams’ rep confirmed to PEOPLE that she and her fiancé, Reddit co-founder Alexis Ohanian, will welcome their first child in the fall. “I’m happy to confirm Serena is expecting a baby this fall,” the rep shared.

 And just days after the baby news, the sports star posted a moving love note to her unborn baby. 
 
 Also at the Ted Talks event, Williams opened up her career plans post-baby. 
 
 “Roger Federer is older than me and he’s still winning everything,” she said about getting back in championship caliber shape. 
 
 “My baby’s going to be in the stands, hopefully cheering for me,” Williams gushed. ||||| Serena Williams is just like us, well, sorta. 
 
 The tennis legend admitted during her Ted Talk with Gayle King that she didn't mean for her pregnancy announcement photo to hit social media—but accidents happen! 
 
 "I asked you about that picture and you said nobody was supposed to see that picture. What do you mean?" King asked. 
 
 "Well, actually it was an accident. 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," the pregnant star explained. 
 
 "I didn't tell a lot of people to be quite honest and I'd been saving it. And you know how social media is when you press the wrong button…and…" 
 
 King interjected, "There it was!"
– Some thought Serena Williams was being coy when she posted the image last week that announced her pregnancy to the world, then soon after deleted it. But it turns out the tennis star had simply never meant for the picture to go public at all, People reports. The tennis star sat down Tuesday with Gayle King at the TED conference in Vancouver, BC, and revealed, as E! Online puts it, that she's "just like us, well, sorta" when it comes to messing up on social media. "It was an accident," Williams confessed about the baby bump reveal now seen 'round the world. She explained how she's been regularly taking pictures of her pregnancy's progress and saving it for herself, except this time around she hit "Send" instead of "Save." "You press the wrong button and…," Serena explained. Williams isn't taking the goof-up too hard, though, noting that she'd planned on sharing the big news in "five or six more days" anyway.
