In the new trailer for the second season of Hulu's "The Kardashians," Kylie Jenner reveals how she struggled after the birth of her son back in February.

In conversation with her sister Kendall, Kylie Jenner gets candid about life after baby number two.

"I should be really happy right now," she tells her sister. "I just had this new baby, but I cried nonstop for like three weeks."

This isn't the first time Kylie has opened up about her postpartum struggles after delivering her son (whose name has yet to be revealed). She's even said her postpartum experience after giving birth to her now four-year-old daughter, Stormi, were nothing like her current experience.

"This experience for me personally has been a little harder than with my daughter," she said on Instagram back in March. "It's not easy mentally, physically, spiritually, it's just crazy."

"And yeah, I didn't just want to get back to life without saying that because I think we can look on the internet—for other moms going through it right now—we can go on the internet, and it might look a lot easier for other people, and put the pressure on us, but it hasn't been easy for me."

She said at the time that she hopes by coming forward with her struggles this time around, other moms will feel less alone.

"It's OK not to be OK. Once I realized that I was putting some pressure on myself...And I just keep reminding myself I made a whole human, a beautiful healthy boy."

In addition to riding that postpartum hormonal wave of emotions, Jenner has also said she was experiencing an intense amount of physical pain months after her son's arrival. She said it made it difficult to get back into her exercise routine.

"4 months postpartum," said back in June. "I have been dealing with tons of back and knee pain this time so it slows down my workouts but I am on a mission to get strong again."

Kylie, who has typically been pretty private about real life as a mom, seems to have realized the importance of sharing her truth this time around. It looks like we'll learn more about the beauty mogul's experience and struggles in season 2 of "The Kardashians" on Sept. 22 on Hulu.

"We have to stop putting pressure on ourselves to be 'back,'" Jenner said this summer. "Not even physically, just mentally, after birth. So yeah, just sending some love. I love you guys!"
