Michelle’s frank talk on miscarriage

Michelle Obama revealed she suffered a miscarriage back when she and husband Barack Obama were trying to start their family.

The former First Lady opened up about the experience in an interview with ABC's Robin Roberts Friday on “Good Morning America.”

“I felt like I failed because I didn't know how common miscarriages were because we don't talk about them,” Obama says in the pretaped interview. “We sit in our own pain, thinking that somehow we're broken.”

Obama, 54, said she and her husband turned to in vitro fertilization two decades ago to have their daughters, Malia, 20, and Sasha, 17.

“The biological clock is real because egg production is limited, and I realized that as I was 34 and 35,” Obama told Roberts. “We had to do IVF.”

Roberts' full interview with Obama is set to air Sunday, two days before the release of Obama's memoir, “Becoming,” in which she addresses topics she discussed with Roberts.
