Serena Williams discussed the harrowing complications she suffered during ― and after ― the birth of her daughter, Alexis Olympia, in a revealing new interview for Vogue’s February issue. Williams said her pregnancy was relatively easy, but the complications began when her daughter was born via C-section after Williams’ heart rate dropped. “Sometimes I get really down and feel like, man, I can’t do this,” the 36-year-old told the magazine. No one talks about the low moments ―the pressure you feel, the incredible letdown every time you hear the baby cry.”
