Reality TV star Kim Kardashian, 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 photograph of her pregnant belly and is clearly feeling down about the situation as she added a sad emoji to her tweet, reports femalefirst.co.uk.

She captioned the photograph: "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 said that she had gained a lot of weight during her latest pregnancy.

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