She told the publication that the problems began after Alexis Olympia's heart rate started to drop during her delivery and it was decided that the best option would be to have Serena undergo an emergency c-section.
Mentioning the names of Caroline Wozniacki, Svetlana Kuznetsova and Angelique Kerber, Williams said that it's important for competitors to genuinely care for and respect one another.
"And then everything went bad".
The next day while still in the hospital, Williams suddenly fell short of breath.
'I was like, a Doppler?
When the ultrasound showed nothing, Williams was sent for a CT scan, which showed several small blood clots on her lungs and she was quickly placed on a drip.
The ordeal continued for another six days.
Serena, who has a history of blood clots, had to go off of her daily anticoagulant medication because of her C-section. She was once again in surgery to have a filter placed into a vein to prevent clots from traveling to her lungs.
"Knowing I've got this lovely baby to go home to makes me feel like I don't have to play another match", she explained. She also didn't have a night nurse to take care of her daughter.
Her husband Alexis Ohanian was more than willing to help with the baby, but felt powerless during his wife's struggle. "I want to teach her that there are no limits".
The tennis superstar and her Reddit co-founder partner Alexis Ohanian welcomed Alexis Olympia Ohanian Jr. in September (17), with the couple marrying two months later in New Orleans.
"Consider for a moment that your body is one of the greatest things on this planet, and you're trapped in it".
On motherhood, Serena admitted to being scared when she was pregnant with regards to whether she was going to be a good mother or not. "No one talks about the low moments-the pressure you feel, the incredible letdown every time you hear the baby cry", she said. "But not yet. Maybe this goes without saying, but it needs to be said in a powerful way: I absolutely want more Grand Slams".
'Sometimes I get really down and feel like, Man, I can't do this, ' she said.
