Forever FLOTUS Michelle Obama revealed she felt "lost and alone" after undergoing a miscarriage 20 years ago. 

"I felt like I failed because I didn’t know how common miscarriages were because we don’t talk about them," Obama told Robin Roberts during an interview on Good Morning America. "We sit in our own pain, thinking that somehow we’re broken."

Now 54, she said that daughters Sasha and Malia, 17 and 20, were conceived through in vitro fertilization (IVF).

"I realized that as I was 34 and 35," the Harvard Law School grad divulged in the ABC special set to air Sunday evening. "We had to do IVF."

The announcement comes ahead of Tuesday's release of Obama's memoir Becoming, in which she details everything from her Chicago childhood, studying at Princeton and Harvard to becoming the country's first Black first lady.

A raw, revealing account of her remarkable life, Becoming is one of the most anticipated political memoirs in recent times. Biographies by first ladies, including Hillary Clinton and Laura Bush, instantly land on best-sellers lists.

The women's rights advocate also divulged the somber periods of her marriage, admitting that the couple sought marriage counseling when their relationship was in danger.

"Marriage counseling for us was one of those ways where we learned how to talk out our differences,” she told Roberts. “I know too many young couples who struggle and think that somehow there's something wrong with them. And I want them to know that Michelle and Barack Obama, who have a phenomenal marriage and who love each other, we work on our marriage. And we get help with our marriage when we need it."

"This was my pivot point," Obama said. "My moment of self-arrest."

Obama does not mince words in her upcoming book about the current administration, describing her shock when she learned Donald Trump would be her husband's successor.

She also condemned Trump for his persistent "birther" crusade which questioned her husband's citizenship. Trump insinuated that President Obama was born on foreign soil rather than in the United States. Although his father is Kenyan, President Obama was born in Hawaii. Mrs. Obama called the accusations bigoted, dangerous and they were "deliberately meant to stir up the wing nuts and kooks."

The primetime ABC exclusive special “Becoming Michelle: A First Lady’s Journey with Robin Roberts,” airs on Sunday, November 11, at 9 p.m. ET. Mrs. Obama's promotional tour begins Tuesday, November 13 at Chicago's United Center, where Oprah Winfrey will join her.
