"I have been very open and honest about my pregnancy struggles," the 35-year old said. "This pregnancy, I'm definitely scared for my delivery, but trying my best to be hopeful and not stress out too much!"

"Last pregnancy, I had a condition called preeclampsia, which is a serious condition you can get during pregnancy," she explained, adding that only five percent of women experience the condition. "It causes your body and face to swell, and that was very uncomfortable for me. I had early-onset preeclampsia and I had to deliver at 34 weeks, almost six weeks early."

Meanwhile doctors have told Kim that it's too risky for her to conceive again, the source says.

"This is definitely the last baby Kim is having herself," the source shares. "Doctors told her getting pregnant again is just too risky. The two pregnancies did so much damage to get body, it's just not worth it. If she wanted more, adoption wouldn't be out of the question."

Last Novermber, the mother of two revealed on her website how complicated it was when she gave birth to her 2-year-old daughter with Kanye West.

"The doctor had to stick his entire arm in [her] and detach the placenta with his hand, scraping it away from [her] uterus with his fingernails," when she gave birth to North. "My mom was crying; she had never seen anything like this before," Kardashian revealed.

Despite the complications she went through, Kanye West's wife is definitely being a hands-on mom to Saint, breastfeeding and "trying to do it all on her own," though she did hire a baby nurse, a source reveals.

"Kim is in love with Saint," the source says. "He is so adorable."

On the other note, when ET caught up with 60-year-old momager Kris Jenner last month at the Hollywood Reporter's 2015 Women in Entertainment Breakfast, where she dished that Kim was strong, but “a little cranky” while giving birth to Saint.
