London: Khloe Kardashian who is married to basketball player Lamar Odom says getting pregnant is a `much harder` process.
`I thought I`d be pregnant by now. We`ve been working at it all year,` femalefirst.co.uk quoted her as saying.
`Getting pregnant is much harder than we thought - but practising making babies is amazing,` she said.
The couple have reportedly started using a fertility monitor so that they know when Khloe is ovulating and what the optimum time is to try.
`Khloe`s been using the monitor for about a month now. They`re trying more actively than ever before. Lamar is very serious about it,` a source said.
