I found out I was pregnant just a few weeks after accepting my job offer. I was scared, and it put some pressure on our marriage but eventually we grew used to the idea.

These were worse than I had experienced before but just went with it. With my son I had several episodes of bleeding and so far this pregnancy was fine.
I was even thinking to myself this may be really not too bad. Then I started having some spotting. I went home angry and upset, and paid for a private scan later that evening.

Standing in the doorway of our soon-to-be-finished nursery, I had a big smile on my face. Being a mum was really the only thing I had ever wanted out of life.

We were having a home birth as I was classed as low risk and I didn’t like the thought of delivering in a hospital – friends of mine had worried me with tales of pushy midwives and not being able to have the birth they had imagined, as they seemed to lose control of their birth plan in a hospital environment, which put me right off!
I had a very clear idea of what I wanted for my labour – low intervention and minimal painkillers as I wanted a water birth at home. We wanted to know now if our child had any additional needs so we had time to study and prepare for its arrival.
