Kim Kardashian Pregnancy Update: Doc Tells Reality Star She's Having Too Much Sex

Maybe she had thought it wrong. Or maybe Kim Kardashian hadn't counted properly enough, when she said that she and her husband Kanye West had sex 500 times a day.

But in a new interview, Kim corrected herself, and put the real number of daily sex to be around 15. However, as Kim's doctor says, that wouldn't have been the only way to become pregnant, so that she can get her daughter North West a small sibling , according to lifeandstylemag.

"The doctor said he thinks I'm having sex too much," she revealed. "He said one time is more powerful...so we've tried everything."

"The doctor said when I have sex I have to lay down for, like, 10 to 20 minutes, so, I just had sex before you guys got here," she told her sisters during the 10th season premiere of "KUWTK," according to latinpost. "He said it takes 10 minutes for a sperm to swim up there. I'm going to wait like 5 more minutes just for this to marinate inside of me."

Frustrated Kim is devastated that sex doesn't lead to whatever she wants. After all, she said, "literally teenagers on meth get pregnant in two seconds. It's crazy. When you don't want to be pregnant, it happens."

Sighing, she said: "I've done everything so perfect to try and get pregnant. There's a list of things you shouldn't be doing and I was perfect for eight to 10 months and now I don't understand."

Her own pregnancy tips include doing some pretty outrageous things that do not seem to be related to giving birth to babies. "I'm going to do everything that I want to do and that includes going platinum," she told 'E! News' "Hopefully I will get pregnant doing all the wrong things. I'm totally changing my tactics.

"I'm over it. I'm over trying, overthinking it, hence why I dyed my hair blonde."

What else could be preventing her from getting pregnant? Her tiny waist, which has pared down completely due to her waist training in the past two moths? Does a slimming technique help?

"Waist training will not affect a woman's fertility, but I would caution against using such a devise to an extreme," Dr. Feingold tells HollywoodLife.com.

"There are no long term damaging effects nor does it reduce likelihood of having a baby," Bruce E. Katz, M.D., Clinical Professor Icahn School of Medicine at Mt Sinai and Director of Juva Skin & Laser Center added.
