“Like a wounded animal, I’d just rather go in a cave by myself, lick my wounds,” Tiffany Haddish told The Washington Post, revealing for the first time that she’s suffered eight miscarriages.

The comedian, 43, has never been shy about sharing her truth with the world. From her book “The Last Black Unicorn” to her stand up specials, Haddish often uses her own pain to educate and encourage others — all while getting a few laughs. But in the Washington Post interview, she opened up about a topic she’s kept private until now.

Miscarriages are actually very common. “Some research suggests that more than 30 percent of pregnancies end in miscarriage, and many end before a person even knows they’re pregnant,” the March of Dimes reported. But repeated miscarriages, like Haddish’s, often result from particular medical issues.

The actress recalled a recent trip to the doctor, telling her nurse, “Well, I’m going, to be honest with you, this would be my eighth miscarriage.” In her case, the cause is a bicornuate uterus.

“I’ve got a uterus shaped like a heart,” Haddish explained. “It just won’t keep anything in.”

Bicornuate uterus is a condition where the uterus develops with “two sides” instead of a single hollow cavity. It’s a rare, congenital condition that can cause complications during pregnancy, and it can only be treated with surgery.

The Cleveland Clinic says that less than 0.5% of women have a bicornuate uterus, and that most of them “won’t be aware they have an irregularly shaped uterus until they’re pregnant and experience several miscarriages.”

Haddish explained that she’d kept her condition private because she didn’t want people to worry about her and hoped to avoid well-meaning questions about how she was doing.
