Kim Kardashian apparently worries her "subconscious" will stop her getting pregnant.

The 34-year-old reality star and her husband Kanye West already have daughter North, who was born in June 2013.

It was recently reported the pair are keen to add to their brood, with Kim apparently eager to do everything she can to speed up the process.

"Kim has been warned the stress of her hectic schedule could hinder her chances of getting pregnant, so she's promised Kanye she'll take a more relaxed approach to work," an insider divulged to British magazine Star.

"She's only eating organic foods, is taking Chinese herbs and having acupuncture three times a week. She has even visited a hypnotherapist in the hope that it will help her subconscious mind to get rid of whatever is blocking her from getting pregnant."

Kim previously admitted that she never thought she would fall pregnant naturally and was willing to have her eggs frozen. Now she hopes baby number two won't need any extra help, just like North.

"Kim and Kanye know Nori was a miracle baby and they're praying they'll be just as lucky second time around," the source continued.

Apparently another reason for wanting to expand their family is that Kim grew up with so many siblings. She has younger sister Khloé and older sister Kourtney, as well as brother Rob and half-siblings Kendall and Kylie.

And there could also be pressure from her husband.

“Trying isn’t the word. Kanye wants to get Kim pregnant, immediately,” a source recently told Hollywood Life. “Kanye has this big dream: He wants to give Kim a baby on her 35th birthday [October 21, 2015] and he’s trying to get her pregnant between now and January in hopes that Kim will be in labour on her birthday.

“Everything about Kanye is original and sentimental. He proposed to her on her birthday and now he wants to give her a second child on the same day next year.”
