Hailey Bieber is feeling a wave of emotions while revealing a new health battle she is facing.

"I have a cyst on my ovary the size of an apple," the model wrote on her Instagram story, along with a picture highlighting her stomach.

The 26-year-old shared that while she doesn't suffer from endometriosis or Polycystic Ovary Syndrome (PCOS), she has had an ovarian cyst "a few times," which she explained is "never fun."

Written beneath the picture of her stomach, Bieber emphasized that she is not pregnant, and any "protrusion" is "not a baby."

"It's painful and achy," she said of the cyst, adding it makes her "feel nauseous and bloated and crampy and emotional."

This is not the first time Bieber has spoken candidly on a health struggle. 

In a YouTube video shared in April, Bieber revealed what happened in March when she suffered a mini-stroke.

"The right side of my face started drooping, I couldn't get a sentence out…Immediately, I thought I was having a stroke."

The scary incident led to the discovery of a heart condition. In that same YouTube video, she revealed she underwent a medical procedure to fix a hole in her heart and that she was "recovering really well."

Months later, her husband musician Justin Bieber revealed that he was suffering from partial facial paralysis and had been diagnosed with Ramsay Hunt syndrome.
