Kim Kardashian West says pregnancy is the ''worst experience'' of her life.

The 34-year-old reality TV star is currently expecting her second child with husband Kanye West but admitted she hates being pregnant.

In a new post on her website KimKardashianWest.com, Kim wrote: ''I'm gonna keep it real: For me, pregnancy is the worst experience of my life! LOL! I don't enjoy one moment of it and I don't understand people who enjoy it.

''Maybe it's the swelling, the backaches or just the complete mindf**k of how your body expands and nothing fits. I just always feel like I'm not in my own skin.

''People just don't tell you all of the gross things that happen during pregnancy or after. Do you know you basically have to wear a diaper for two months afterwards! LOL! No one told me that! #SoSexy.''

However, Kim - who already has a two-year-old daughter North, insisted that it is worth it in the end.

She completed her blog post by writing: ''Really, it is all SO worth it when you have your precious baby in the end! So for all my complaining, it's 100 percent worth it and more!!!''
