Kim Kardashian's pregnancy days are over for good, a source close to Kim exclusively tells ET.

Doctors have told the 35-year-old reality star that it's too risky for her to conceive again, the source says. It's no secret that Kim has had difficult pregnancies with both her children, the now two-year-old North West, and Saint West, whom she welcomed last month.

"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 month, a source confirmed to ET that Kim recently dealt with the same complications during labor that she faced when she delivered her daughter in 2013. Kim suffered from placenta accreta, a condition in which the placenta remains attached to the wall of the uterus, instead of coming out after the birth of the baby.

See Kim Kardashian's evolution through the years:

In a post Kim wrote on her website in November, she revealed that her 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," Kim revealed.

Kim also ended up having to move up the due date of her second delivery from Christmas Day -- when doctors originally planned on inducing labor -- to Dec. 5, due to the high risk of complications. North was also delivered early due to Kardashian's health concerns -- including preeclampsia -- and was born nearly six weeks early.

Clearly though, it was all worth it. The source says that Kim 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.

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

But not everything is picture-perfect in the Kardashian household. Kim and her husband, Kanye West, are more than ready to move out of her mother Kris Jenner's home in Calabasas, California, the source says. The couple's been living with Kris after ordering extensive renovations to their new home in Hidden Hills, California.

"They are so ready to get out of there," the source says. "No one can understand what is taking so long for their new house to be finished. They bought the most magnificently beautiful home but still ripped everything out to make sure it's done how they want it. It's taking much longer than expected."

ET caught up with Kris 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. Watch below:
