But she explained in more detail that the unexpected pregnancy was the result of a relationship she had with an older New York man while she was a student at the LaGuardia High School of Music & Art and Performing Arts in Manhattan. The decision to end the pregnancy "haunted" her.
"I was a teenager. It was the hardest thing I'd ever gone through," she said in the interview, which will be published on Friday. "It'd be contradictory if I said I wasn't pro-choice. I wasn't ready. I didn't have anything to offer a child."
Minaj suggested that these revelations come reluctantly. But with her rising fame, she noted that millions of people are suddenly scrutinizing and judging her every word.
Minaj was also asked why black hip-hop artists seemed largely reticent to comment on the recent wave of protests following the non-indictment of two white police officers in the deaths of two unarmed black men, Brown and Garner.
She noted that hip-hop's cultural power has diminished since Public Enemy made a statement with "Fight the Power."
"People say, 'Why aren't black celebrities speaking out more?' But look what happened to Kanye (West) when he spoke out. People told him to apologize to (President George W.) Bush!" Minaj said.
"He was the unofficial spokesman for hip-hop, and he got torn apart," she added. "And now you haven't heard him speaking about these last couple things, and it's sad."
"Because how many times can you be made to feel horrible for caring about your people before you say, '(Expletive) it, it's not worth it, let me live my life because I'm rich, and why should I give a (expletive)?'" she added.
