Michelle Obama’s IVF story
Former First Lady Michelle Obama has released a memoir in which she reveals difficulties about her marriage and pregnancy with her two daughters.
In the book, Becoming, Mrs Obama reveals that she had a miscarriage and used in vitro fertilisation to conceive both children, Malia and Sasha.
Mrs Obama told ABC's Good Morning America she felt "lost and alone" after her miscarriage 20 years ago.
She also criticised Donald Trump for "putting my family's safety at risk".
Mrs Obama and her husband, former President Barack Obama, sought couples therapy, she also revealed for the first time in her 426-page book, which will be released on Tuesday.
Following publication, the first African-American first lady will tour 10 cities including London.
Mrs Obama, a former lawyer and hospital administrator, told ABC that after her miscarriage, "I felt like I failed because I didn't know how common miscarriages were because we don't talk about them.
"We sit in our own pain, thinking that somehow we're broken," she said, adding that "it's important to talk to young mothers about the fact that miscarriages happen".
She said that when she was around 34 years old, she realized that "the biological clock is real" and that "egg production is limited", which made her decide to seek in-vitro fertilisation.
"I think it's the worst thing that we do to each other as women, not share the truth about our bodies and how they work," Mrs Obama told ABC's Robin Roberts on Good Morning America.
On her marriage
Mrs Obama revealed that the couple's relationship struggled at times, especially after her husband joined the state legislature, leaving her at home where she was forced to administer IVF shots herself.
"Marriage counselling for us was one of those ways where we learned how to talk out our differences," she told ABC.
"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."
She also describes falling in love with Mr Obama one summer night in Chicago.
"As soon as I allowed myself to feel anything for Barack," she writes, "the feelings came rushing - a toppling blast of lust, gratitude, fulfilment, wonder."
