Kourtney Kardashian's unplanned pregnancy
forced the shocked reality TV star to make one of the most difficult decisions in her life: Would she have the baby or terminate the pregnancy?
"I definitely thought about it long and hard, about if I wanted to keep the baby or not, and I wasn't thinking about adoption," Kardashian, 30, who was shooting E!'s Kourtney & Khloe Take Miami
at the time, tells PEOPLE exclusively. "I do think every woman should have the right to do what they want, but I don't think it's talked through enough. I can't even tell you how many people just say, 'Oh, get an abortion.' Like it's not a big deal."
Scott Disick, the baby's 26-year-old father, was supportive either way. The pair had split in November after two years of dating, but reconciled shortly after finding out she was pregnant. "He wanted me to talk about it more, but I just kept to myself," she says. "He said, 'I really want you to keep it, but I will support you whatever you decide to do.'"
Confused and concerned, Kardashian says, "I called my best friend crying, and I was like, 'I don't know what to do.' She said, 'Call your doctor, and at least find out the risks and stuff.' " So Kardashian discussed abortion with her physician, and then headed to the Internet to do further research.
"I looked online, and I was sitting on the bed hysterically crying, reading these stories of people who felt so guilty from having an abortion," she recalls. "I was reading these things of how many people are traumatized by it afterwards."
After scouring the Internet, Kardashian says she started to realize that an abortion wasn't an option for her. "I was just sitting there crying, thinking, 'I can't do that,' " she says. "And I felt in my body, this is meant to be. God does things for a reason, and I just felt like it was the right thing that was happening in my life."
Kardashian says she did some intense soul-searching. "For me, all the reasons why I wouldn't keep the baby were so selfish: It wasn't like I was raped, it's not like I'm 16. I'm 30 years old, I make my own money, I support myself, I can afford to have a baby. And I am with someone who I love, and have been with for a long time."
Although Kardashian sought out the advice of others, she says it was her decision – and hers alone – that was the most important.
"I really wanted to think it through for myself, and not hear what my sisters were saying, or what Scott was saying. Even though I took it all in, I wanted it to be my decision," she says. "My doctor told me there is nothing you will ever regret about having the baby, but he was like, 'You may regret not having the baby.' And I was like: That is so true. And it just hit me. I got so excited, and when I told Scott he was so excited. But I think if I had said I'm not going to keep it, I really think he would have pushed me into keeping it."
