Not wanting to worry her visiting mother, Williams stepped into the hall and flagged a nearby nurse, insisting that she needed an IV with heparin, a blood thinner, and a CT scan to check for clots.
'I was like, a Doppler?
The ultrasound revealed nothing, and according to Vogue, Williams reiterated: "I told you, I need a CT scan and a heparin drip". They then performed the scan to find multiple blood clots in the tennis star's lungs.
"When I'm too anxious I lose matches, and I feel like a lot of that anxiety disappeared when Olympia was born", she said.
First, her C-section wound reopened after a coughing spell caused by the clots in her lungs.
Finally, Serena was allowed home, but spent six weeks in bed.
She revealed that she had an emergency c-section when giving birth to Alexis Olympia.
Williams was supposed to give a shot at defending her title at the Australian Open later this month but pulled out on Friday, saying she was "super close" but still not at the level she needs to be.

"There hasn't been a clear number one since I was there".
"After competing in Abu Dhabi I realised that although I am super close, I'm not where I personally want to be", she said in a statement on Snapchat.
"I hate playing her because she gets this look on her face where she just looks sad if she's losing - solemn", Serena said.
