During Thursday’s episode of the Hulu seriesThe Kardashians, the Poosh founder opened up to momKris Jennerabout wanting to have a child with Barker.

However, things were not going as planned for Kardashian, who revealed that she’s currently facing complications in her IVF journey, and experiencing depression as a result.

During a visit to Kardashian’s home, Jenner sat down with her eldest daughter and asked how her doctor’s appointments were going.

Speaking to her mom, Kardashian continued, “Every single person on social media is always like, ‘Kourtney’s pregnant, Kourtney’s pregnant, Kourtney’s gained so much weight.’ I’m like, it’s so rude to comment on people when you have no idea what they’re actually going through.”

“The medication that they’ve been giving me, they put me into menopause,” she added.

In a confessional, Kardashian added: “I think because I’m so clean and careful with what I put into my body, it’s just having the complete opposite reaction and is working as a contraceptive instead of helping us.”

The news came as a shock to Jenner, who told her daughter, “I feel like I’ve never seen you happier so the depression thing surprises me.”

Kardashian was in agreement, explaining that the reason she and Barker “want it so badly” is because “we want to make something together.”
