We feel like we’re in a very good spot,' she added Andrew, 27, posted a similar announcement on his Instagram page, opting to share a video that starts at their feet and pans up to reveal Shawn's baby bump and the tiny white sneakers they are holding in their hands. 'Coming 2019: @theeastbaby,' the Washington Redskins player captioned the footage. The couple, who wed in 2016, also filmed a video announcement titled 'pregnancy + hope' for Shawn's popular https://www.youtube.com/watch?v=cHs1ffWg8-E&t=37s channel, which has more than 712,000 subscribers. Big news: On Thursday, Shawn shared a photo of herself cradling her baby bump in a floral dress while her husband, Andrew, hugs her to announce their pregnancy Family of three: The excited parents-to-be already started an Instagram account for their little one, @theeastbaby, which is filled with photos from their maternity shoot In a series of videos posted to Instagram Stories, Shawn hinted that she had been 'keeping a pretty big secret' from her followers and urged them to check out their YouTube video detailing their journey and how she told Andrew they are having a baby. 'It's been a long one considering two years ago we lost our baby, and we have been blessed with another,' she said. The YouTube video was filmed on February 17, and at the start of the clip Andrew holds up a positive pregnancy test for the camera to see. The football player and his wife then look at each other and kiss. 'We are pregnant!' she says. Surprise! The couple also filmed a video announcement titled 'pregnancy + hope' for Shawn's popular YouTube channel, which has more than 712,000 subscribers Caught on camera: The video, which was filmed on February 17, shows the moment Shawn handed Andrew her positive pregnancy test and told him that she was pregnant Caught off guard: 'You serious? Are you serious, babe?' he asked after Shawn handed him the pregnancy test in front of their friends 'I am pregnant,' she reiterates. 'I don't know how you say that. Is it we or I?' Shawn suffered a miscarriage in October 2017 and documented her heartbreak in a candid video shared on her YouTube channel. Andrew explains that this baby has been a 'long time coming' and they 'couldn't be more excited.' The former gymnast says she had a feeling she was pregnant because her stomach was upset and she was suffering from migraines every morning. Sugar also repulsed her and made her sick to her stomach, which was a symptom she had during her last pregnancy. 'I took three pregnancy tests all within the time frame of when they say you can and they call came out negative,' she recalls. Joyous moment: Andrew lifted his wife up into his arms and gave her a big kiss Happy: Shawn was in shock and excitedly shaking after telling Andrew the news Parents-to-be: The couple said they are excited to be expecting a child, but they both admitted that they were more guarded this time because of Shawn's previous miscarriage https://www.youtube.com/embed/cHs1ffWg8-E?feature=oembed Shawn says she ended up taking one of the 'cheapest' pregnancy tests on the market while Andrew was working out, but the line was so blurry she wasn't sure what it meant. She grabs the test to show Andrew and their viewers how faint the line is, and Andrew insists she should have called and told him what was going on — even if she wasn't sure. Shawn ended up blowing off the results until they went over their friends Josh and Chelsea's home. They are both doctors, and she told Chelsea that she had taken a cheap pregnancy test but was confused by the results. Chelsea had her take a First Response test, and Shawn says within 10-seconds it was clear that she was pregnant. Honest: Shawn documented her heartbreak over her miscarriage in a YouTube video that she shared on her channel in 2017 Loss: The former gymnast was physically sick after her miscarriage, and she shared footage of herself lying by the toilet in her bathroom Looking back, Shawn says she was in shock and didn't know how to walk out and act normal in front of her husband, so she decided to tell him in front of their friends, who gladly filmed the moment. Shawn sat Andrew down at the counter and handed him her positive pregnancy test, and he was immediately filled with joy. 'You serious? Are you serious, babe?' he asked, giving her a hug and a kiss. Reflecting on the moment, Andrew explains that last time he was 'terrified,' but now he is 'cautiously excited' and proud of his wife for opening up about her miscarriage. All smiles: Shawn and Andrew are both cautiously optimistic about her pregnancy, and he revealed that she is already listening to Mozart to try and make their baby a 'genius' Look of love: Andrew told Shawn that she is going to be an 'awesome mom,' while she insisted he is going to be the 'best dad' Thrilled: Nastia Liukin, Shawn's best friend and teammate at the 2008 Summer Olympics in Beijing, celebrated the news on Instagram with a Boomerang video of them dancing Looking to the future: Nastia, 29, said she can't wait to spoil Shawn and Andrew's baby 'That message really resonated with a lot of people,' he tells her. 'I'm absolutely terrified,' Shawn admits. 'It's natural for anybody who has experienced pain or loss to guard their hearts when things happen again. Throwback: Shawn is pictured competing on the floor exercise during the women's team final at the 2008 Olympic Games in Beijing 'I can naturally feel my heart is guarding itself because I don't want to go through that again. I was so new and naive to the whole situation that it was just raw emotion,' she says of miscarrying. Andrew reveals that Shawn is already listening to Mozart to try and make their baby a 'genius.' 'I'm so excited to be doing this with you,' he tells her. 'There is no one else I'd rather be doing this with. You're going to be an awesome mom. 'You're going to be an awesome daddy,' she responds. 'You're going to be a dad. You're going to be the best dad.' Nastia Liukin, Shawn's best friend and teammate at the 2008 Summer Olympics in Beijing, celebrated the news on Instagram with a Boomerang video of them dancing together. 'Doing a little happy dance because my best frannnn is pregnant!!!!' the 29-year-old captioned the clip. 'So freaking happy for you @shawnjohnson @andrewdeast!!!
