"After marrying Alex I had only one thing on my mind - having another baby. I'd love to have another four, in fact. But by April 2010, after we had been trying for eight months, I became so worried we made an appointment with a fertility doctor.
We were having ICSI (Intra-cytoplasmic Sperm Injection) which has a 65% success rate. It would involve me injecting hormones to stimulate egg production.
After two weeks, once the eggs were ready, the doctor would retrieve them. Just before that procedure, Alex would provide a sperm sample. An individual sperm is selected and injected into each egg. Then, when the embryos have started to grow, it's time to put them back into the uterus. I was anxious, but I thought, 'Surely this will work as I've had three children?'
As I left the clinic I felt a surge of excitement. I thought, 'I'm pregnant!' And in a way I was, because now I had the embryos inside me all they had to do was grow.
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. I know I'm lucky to have three beautiful children. While Alex doesn't yet have a biological child, he is still part of a family with kids. I am sure we'll have a baby together one day. If we aren't successful in our attempts then we will adopt."
Our heart certainly goes out to them during what we can imagine to be a very difficult time, but we hope that both Katie and Alex focus on the three children that they already have.
