Kardashian, 34, who is expecting her second child with husband Kanye West, faced fertility challenges to conceive again, reported Glamour magazine.
"I didn't know that I was going to be so open with (my fertility challenges). It's been really emotional. One doctor told me I would need my uterus removed after I had another baby-I could only have one more. One was like, 'You should get a surrogate.' The other one was like, 'Oh, no, you'll be fine.'
"Then I called my doctor, and he's like, 'You know what? I believe -- we'll get through it.' There are definitely times when I walked out (of the doctor's office) hysterically crying, and other times when I was like, 'Okay, everything's looking good, it's going to be this month!' The waiting and waiting has been a roller coaster," she said.
"I'm a completely different person. I don't know if it's growing up or being with Kanye, who's more private, but I try and live my off time as privately as possible. I used to enjoy the spotlight. If I had a day off from filming, I didn't know what to do. Now I enjoy my family time so much, there is this sense of, if it all went away, and I was just a mom, I would love my life," she said.
