Kylie Jenner reveals her baby was 'falling out' months before birth

Motherhood for most women is no picnic, just ask Kylie Jenner.

In a May 13 episode of "Therapuss" with Jake Shane, the "The Kardashians" star opened up about the difficulties surrounding her second pregnancy, namely the "really bad" back issues she experienced post-pregnancy.

"I have had chronic back pain for like three and a half years. It's just starting to get better," Jenner said on the podcast. "But my son, my last pregnancy, it like really took me out."

Jenner, 28, shares two children, 4-year-old Aire and 8-year-old Stormi, with ex-boyfriend, musician Travis Scott.

"It was like 12 weeks into the pregnancy. I just woke up one day and I'm like 'Oh, I really can't walk.' And I had like crazy Sciatica pain and crazy lower back pain," Jenner added.

Despite having "high expectations" about how her second pregnancy would go, as she was in the best shape of her life, Jenner admitted that her first pregnancy was "a breeze."

"I couldn't leave my bed anyway because I was like in so much back pain and Sciatica pain," Jenner said. "And lots of things were happening with my vagina. I was three centimeters dilated for like a month and a half, two months. The baby was like falling out. And my doctor's like, 'you have to stay in bed.'"

In the end, Jenner said it was all worth it because she gets to see her kids grow up.

"It's the best," she said.

Kylie Jenner was 'really scared' to break pregnancy news

Jenner, who became pregnant with Stormi at 19, recalls being "freaked out" at the prospect of telling her parents that she was expecting.

"I was really scared to tell my parents," Jenner said. "I was really scared but there was something just inside of me that knew... That I wanted to do this."

"I had to make a decision for myself. Like, what do I really want? What can I handle? And even if I have to do this alone or however, like this is the choice that I'm gonna make... and then I told my mom," she added.

According to Jenner, her parents, Caitlyn and Kris Jenner, were supportive, adding that "no one was like angry at me."

"No one... it was just, it was crazy, crazy times," she said.
