Pink reveals she had a miscarriage when she was only 17

Pink has always been an open book when it comes to her life and music, but she opens up like never before on her newly released album, Hurts 2B Human.

"Since I was 17, I've always hated my body. And it feels like my body's hated me. Can somebody find me a pill to make me un-afraid of me?" she sings on her new single 'Happy'.

However, the meaning of the song is anything but as the 39-year-old revealed to USA Today that it was about the miscarriage she suffered as a teenager.

"The reason I said [that] is because I've always had this very tomboy, very strong gymnast body, but actually at 17 I had a miscarriage," she told the publication. "And I was going to have that child.

"But when that happens to a woman or a young girl, you feel like your body hates you and like your body is broken, and it's not doing what it's supposed to do."

In the interview, Pink -- who now shares two children with husband Carey Hart -- revealed that she actually suffered a few miscarriages when she was younger.

"I've had several miscarriages since, so I think it's important to talk about what you're ashamed of, who you really are and the painful s---," she said, adding, "I've always written that way."

If anything, writing about heartbreak in her music helps the singer deal with her pain, as does therapy.

"I believe in self-confrontation and just getting things out," she said. "What I love about therapy is that they'll tell you what your blindspots are. Although that's uncomfortable and painful, it gives you something to work with."
