Millie Mackinstosh has opened up about battling "severe anxiety" during her pregnancy.

The former Made in Chelsea star, who is expecting her first child with husband Hugo Taylor, took to social media to tells her followers she has recently been gripped by "unexplainable fear" related to childbirth and parenthood.

In a candid Instagram post, she wrote: "Trying to keep on top of my mental health is proving a little tricker than usual. I'm still practicing mindfulness and daily meditation (as I normally would) but have had moments of severe anxiety on multiple occasions.

"I have found over the last few months that I have unexplainable fear which constantly switches from 'something is wrong with the baby' to 'how I will cope when the baby arrives' and don't get me started on the 'BIRTH'!

"I'm sure all new mums go through this and I am no different but would be great to hear from any of you who have been through similar things or have any suggestions on how to lessen these worries. Recommendations for good books & podcast always welcome."

The 30-year-old reality TV star also opened up about the physical symptoms she has been suffering since becoming pregnant.

She wrote: "My pregnancy journey so far... I'm not going to lie it's been a bit of an emotional roller coaster, bursting into tears for no apparent reason has become a weekly occurrence (sorry Hugo!) coupled with nausea, vomiting (not just in the morning - the evening sickness was worse for me) heartburn, breakouts, headaches, mood swings, bloating, insomnia, seriously sensitive boobs, tiredness, cravings, sciatica and a constant metallic taste in my mouth which makes everything taste disgusting!"

The couple announced that they were expecting their first child, a baby girl, in November.
