Jessie J shared details about her miscarriage and how she performed a show the next day after getting the painful news.

"Woke up one morning and I was like, 'Oh, I don't feel right,'" she recalled on the latest episode of "The Diary Of A CEO," which was released Monday on YouTube.

The 34-year-old singer, whose real name is Jessica Ellen Cornish, further explained, "I still had very intense nausea, [but] I just knew something wasn't the same."

Jessie recalled there was "that dreadful silence when you first have a scan and they kind of don't say anything."

"I was like, 'Just tell me the truth. What's going on?'" Jessie said about her doctor's appointment. "She said, 'Your baby's heartbeat is very low and there's this ring, [which]... often means the baby will have some type of disability or deformity.'"

The doctors initially told the singer that the baby was "still there." Jessie visited another doctor as she didn't feel right. "He did another scan and he said, 'I'm really sorry there's no heartbeat,'" Jessie recalled. "That was within three, four hours of the first one."

The singer said she performed at a show the very next day. "I remember just going [home] and not processing it," she said. "And then the next day I went straight into glam, I did the soundcheck... I did the show."

She explained the difficulty she had in processing the "physical painful, emotional painful experience."

"When I got in the car after the show by myself, and I got home, and I opened my front door, and I closed the door, I fell to my knees," she recalled. "That was the worst moment of the whole experience, me realizing that, other than my career, being a mother and having a child has been the biggest excitement of my life."

The "Bang Bang" singer said she has always been "super maternal" and "loves children." Following the incident, she felt very "lonely."

Jessie first announced the tragic news on Instagram last November. However, she later deleted her post.
