She lost to Venus in the third round at Indian Wells and to Japan's Naomi Osaka at Miami in her WTA returns."I'm sure there are some moments in there that I'm not excited about. But that's what it's all about," Williams said. "The camera follows you. You have to just allow yourself to just be."Williams revealed in an interview with Vogue that she suffered a pulmonary embolism after her daughter was born and spent six weeks recovering with bed rest."I chose now to share these moments because I was going through something different in my life," Williams said. "I always wanted to get it down in a documentary so I can always say to my daughter, 'Olympia look at all of these moments.'"Among the behind-the-scenes footage included in the presentation are wedding dress fittings, time with her baby and husband and pets plus wedding photos and even images of her in the hospital as well as seeing Olympia for the first time.
