The Keeping Up With the Kardashians star revealed on her website that complications from her previous pregnancy with daughter North put her at a higher risk factor for experiencing them again when she gives birth to her second child with Kanye West.
"I have been very open and honest about my pregnancy struggles," the 36-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."
While the delivery when smoothly, the reality star experienced further complications once North was born. Warning: the details in this next part may be a little graphic for some.
"My placenta stayed attached inside my uterus, which is a condition called placenta accreta," Kim revealed. "This is a high-risk condition that happens when the placenta grows too deeply into the uterine wall."
"My doctor had to stick his entire arm in me and detach the placenta with his hand, scraping it away from my uterus with his fingernails," she added of the painful experience. "My mom was crying; she had never seen anything like this before."
"They say that this is what some women died from as a result of childbirth back in the day, without proper care. I'm so thankful that my doctor was able to catch this and address the issue immediately," Kim continued, adding that the followup surgeries after this event made conceiving again very difficult. "I have amazing doctors that helped me through the entire process and I'm so grateful I was able to conceive again!"
Of course, one of Kim's biggest fears is that she might have to go through all of that again.
"With the issues I had last time, my risk of having preeclampsia and placenta accreta are increased and there's not a whole lot I can do to prevent it, so my anxiety is a little high leading up to my delivery," she admitted.
"I have some days I get SO scared but then I speak to my doctor, Dr. Paul Crane, and he always calms me down," she said.
Kim added that she may have to get a hysterectomy after the birth, although she is hopeful it won't come to that. The mom previously discussed the possibility in August, saying, "I think we’re just gonna go day by day, see how overwhelming it is, and see how the delivery goes."
"Hopefully, this time, I just have a healthier pregnancy," Kim told ET in June. "I'm just going to try to enjoy it."
Meanwhile, Kim is preparing to give birth to a very big baby boy by Christmas! The reality star wrote in October that the pregnancy has her feeling like "a f**king whale," and later revealed how much weight she's put on while expecting. Watch the video below.
