Katie Price has spoken for the first time about her anguish over her failed attempts to conceive a child with husband Alex Reid.
The 32-year-old mother of three says she even decided to have IVF treatment after failing to fall pregnant with her cage-fighter husband.
Her new autobiography, You Only Live Once, being serialised in the Daily Mirror, describes how Katie is more determined than ever to have a baby with her husband.
'After marrying Alex I had only one thing on my mind – having another baby. I'd love to have another four, in fact,' she writes.
'But by April 2010, after we had been trying for eight months, I became so worried we made an appointment with a fertility doctor.'
Katie decided to undergo ICSI (Intra-cytoplasmic Sperm Injection). She describes how she overcame her needle phobia to have a series of painful injections in a bid to fall pregnant.
ICSI involves stimulating egg production. A sperm sample is selected and injected into the egg before the embryo is put back into the uterus when it starts to grow. It has a 65 per cent success rate, but Katie and Alex's first attempt proved disappointing. Just nine of their eggs had taken – the usual number for a successful attempt is 12 or 13.
However, on the second attempt, Katie believed the process had been more successful.
She says: 'I convinced myself I was having twins. I didn't care about feeling so bloated, uncomfortable and unattractive. If I was pregnant then none of those things mattered.
'For the first few days I held on to the feeling of optimism, but then the waiting got to me. Then I started experiencing stomach cramps and bleeding.
'Alex and I had been so hopeful, so excited, and now all our dreams were dashed.'
Katie recalls one particularly emotional phone call with her husband following the disappointment when Alex asked her if she loved him any less because they were having difficulties conceiving.
She says: 'I told him, "Alex, don't EVER think like that. I love you, and I'm with you whatever happens. We will have a baby one day; we'll do whatever it takes. We are in this together.
'If we aren't successful in our attempts then we will adopt.'
