Los Angeles - Kim Kardashian West's doctor has warned her she is having too much sex.

The Keeping Up with the Kardashians star and husband Kanye West - who already have 20-month-old daughter North together - have been sleeping together up to 15 times a day in a bid for her to get pregnant again but have been advised to cut down by specialists.

Kim admitted: "The doctors said he thinks I'm having sex too much. He said one time is more powerful...so we've tried everything."

The 34-year-old beauty is baffled as to why she hasn't conceived yet and has decided to stop following the rules in a fresh attempt to get pregnant.

She told E! News: "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.

"I'm going to do everything that I want to do and that includes going platinum. 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."

And Kim is particularly baffled why people who don't want children seem to conceive so easily.

She joked: "Literally teenagers on meth get pregnant in two seconds. It's crazy. When you don't want to be pregnant, it happens."
