The 'Keeping Up With the Kardashians' star - who is expected to give birth in the coming weeks - has been struck down by a sinus infection and flu.

She took to Twitter to post a picture of her pregnant belly and is clearly feeling down about the situation as she added a sad emoji to her tweet.

The raven-haired star - who is carrying her second child with husband Kanye West - added the caption: "37 WEEKS x SINUS INFECTION x FLU = [sad emoji] (sic)"

Kim has been pregnant longer with her second child than she was with first baby, two-year-old North West, after she was forced to give birth to the little one five weeks early.

It is well documented that the 35-year-old star doesn't enjoy being pregnant much, having previously described it as the "worst experience of my life".

And last month, Kim revealed she had piled on 52lbs during her latest pregnancy.

She tweeted: "Ok I'm 52 lbs up today....and I still have 6 weeks to go! I got my work cut out for me!!!! (sic)"

The reality TV star previously blasted: "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. (sic)"
