In her new Netflix documentary, HomecomingBeyoncé opened up about what she calls an “extremely difficult pregnancy” with twins Rumi and Sir — including her battle with preeclampsia, a pregnancy condition that causes high blood pressure and can lead to serious complications.

“My body went through more than I knew it could,” the 37-year-old admitted in the documentary, which chronicles the singer’s monumental Coachella 2018 performance that won over the world. Bey revealed that she was scheduled to headline the festival in 2017, but after finding out about her pregnancy in 2016, she had to postpone.

“I was supposed to do Coachella the year prior but I got pregnant unexpectedly,” she explained in the doc. “And it ended up being twins which was even more of a surprise.” Her complicated pregnancy wasn’t an easy one, but their birth was also far from flawless.

“In the womb, one of my babies’ hearts paused a few times so I had to get an emergency C-section,” she revealed. The difficulties didn’t stop there — once Bey was back and ready to try her hand at Coachella again, she had to do some work to get her groove back.

“You know, a lot of the choreography is about feeling, so it’s not as technical, it’s your own personality that brings it to life. That’s hard when you don’t feel like yourself,” she confessed. “I had to rebuild my body from cut muscles. It took me a while to feel confident enough to … give my own personality.”

It was a slow start — and her children were in the forefront of her thoughts the whole time. “In the beginning, there were so many muscle spasms and just internally, my body was not connected. My mind was not there. My mind wanted to be with my children,” she continued. “What people don’t see is the sacrifice.”

But the struggle was worth the reward of coming back to the stage in such a profound way. “It’s my first time home back home on the stage after giving birth; I’m creating my own homecoming, and it’s hard,” she said. “There were days that I thought I’d never be the same. I’d never be the same physically, my strength and endurance would never be the same.”
