Khloe Kardashian is worried people think she is "barren".
The 26-year-old socialite - who married Los Angeles Lakers player Lamar Odom in September 2009 - is concerned she may be "letting people down" by her inability to fall pregnant, and is considering going to see a doctor in the future about her fertility issues.
She told Life & Style magazine: "I feel like I'm letting people down. Other people are so into my getting pregnant and want it to happen. A lot of blogs and magazines even thought I got married because I was pregnant. Now they probably think I'm barren. I get so stressed out about it!
"Lamar so wants to have kids, and I do too. But 'trying' to have a baby is so serious. We've been trying for only a couple of months. If a couple of years go by and it still hasn't happened, then I'll go to the doctor to see if something's wrong."
However, if she did fall pregnant, Khloe admitted she would be "over the moon excited" at the prospect of becoming a mother.
She added: "I guess it's just not my time yet. I'm not desperate to have a baby right now, but if I got pregnant tomorrow, I'd be over-the-moon excited."
