Former first lady Michelle Obama on Friday revealed that she suffered a miscarriage 20 years ago and used in vitro fertilization to conceive her two daughters, Malia and Sasha.

Michelle Obama said she felt “lost and alone” after her miscarriage, in a new interview aired on ABC’s “Good Morning America.”

{mosads}The former first lady said she felt like she “failed because I didn’t know how common miscarriages were because we don’t talk about them.” 

“We sit in our own pain, thinking somehow we’re broken,” she told ABC’s Robin Roberts.

She said her and former President Obama “had to do IVF” to conceive their two daughters, who are now 20 and 17.

She told Roberts that she thinks that women not sharing their experiences with infertility is the “worst thing we do to each other as women.”

The revelation came amid Michelle Obama’s promotional tour for her new memoir “Becoming,” which will be released on Tuesday.

“It turns out that even two committed go-getters with a deep love and robust work ethic can’t will themselves into being pregnant,” she wrote of her experience.
