Myleene Klass suffered four miscarriages before having her "rainbow baby" Apollo

She wrote on Instagram: "On national babyloss-miscarriage day, @chrissyteigen gave me the courage to write.I am Mama to 7 babies, Ava, Hero, Apollo my rainbow baby and 4 little stars in the sky.

"I know after my own MC’s how I scoured the internet for stories similar to mine for peace, reassurance.I hope this helps even one lost soul.(sic)"

Myleene reflected on the "trauma" and "shock" she went through with each miscarriage.

She continued: "#1.At the airport, flying home for a D&C.I’d started bleeding heavily at 10wks on holiday.

"The scan was the saddest sight I’ve ever seen in my life.The first and last time I saw my baby.

"As the doctor pushed the camera on my belly, the familiar black and blue image of my baby sprung onto the screen, then started to sink and slowly floated down, til it just hunched over. I knew. ‘I’m sorry there’s no heartbeat’.

"The feeling is nothing short of traumatic, shock.At my D&C I was asked to confirm the procedure.I cried so hard the nurse held my hand and answered for me.They taped my bracelet to my wrist, two gold swallows.It made me sob. Swallows love for life and always come home.

"I told the anaesthetist to please make sure I wake up as I’m a mum then I cried again at what they were going to take out.I woke to emptiness and the horror of what had happened.I felt I’d failed my baby and my partner.

"#2.The second time was worse if that’s possible, I thought I’d had my ‘1 in 4’ experience.This time,the baby had stopped growing at 10wks,completely unrelated to the first MC ‘so it’s just bad luck’. I didn’t take my eyes off the fire alarm on the ceiling, lest I break completely. Walking past the pregnant women in reception was torture.

"This D&C was no less traumatic. Infact,the familiarity of it cut deeper.The ‘wishes to dispose of the products of pregnancy’ form, the walking to theatre,the ugly socks.Having everything one minute, a name, a school, then nothing.

"The third,I miscarried at work. The fourth,the loo. (sic)"

The former Hear'Say singer admitted doctors couldn't explain why she had suffered so many miscarriages, but "took no chances" when she fell pregnant again with her son.

She added: "Whilst I could get pregnant, there was no explanation for why I couldn’t keep them.The Dr’s took no chances with Apollo.I injected countless,endless hormones into my belly to keep my placenta working.He signifies everything good in the world to me,my miracle.

"To my friends and Mamas who have experienced this, you are the strongest women I know. Thinking of you today(sic)"
