In a message to followers, she wrote: ‘At the beginning of the year, I had a miscarriage which left me heartbroken.
‘I feel incredibly blessed to be pregnant again but I’ve also felt like a bag of nerves.
‘Fertility issues can be really hard for many people, particularly when on platforms like Instagram it can look like everything is only ever going well.
‘I found it a real comfort to hear from people who had also experienced loss so I hope that in some very small way sharing this might help others too.’
The couple were last seen in public together at England’s Euro 2020 semi-final with Denmark at Wembley earlier this month.
She and Mr Johnson, 57, welcomed their first baby, Wilfred, at the end of April last year.
Following the birth, she praised the staff who delivered her son, thanking UCLH on International Day of the Midwife, captioning: ‘A big thank you from me too! You guys are incredible.’
The couple named their son Wilfred Lawrie Nicholas Johnson, after their grandfathers and the hospital doctors who treated the Prime Minister for coronavirus.
Carrie Symonds has announced she is pregnant with her second child with Boris Johnson
Mr Johnson married his partner in a secret ceremony at Westminster Cathedral back in May this year, in front of a handful of close friends and family.
It meant he became the first Prime Minister to marry in office since Lord Liverpool married Mary Chester in 1822.
Ms Symonds gave birth to her son in London last year with her now husband at her side, days after he himself had been released from medical care following a lengthy battle with coronavirus.
In a heart-warming Instagram post revealing the boy’s name, Ms Symonds said that the middle name Nicholas was a tribute to two NHS doctors, Dr Nick Price and Dr Nick Hart, who ‘saved Boris’ life last month’ following his personal fight against Covid.
