As a second blue line appeared on the pregnancy test, I felt I was having an out-of-body experience. I couldn’t be pregnant.

My daughter, Heidi, was only nine months old, and I’d recently become a single mother since splitting with her dad.

I’d taken the test as a last resort, because I was regularly experiencing a strange fluttering sensation in my stomach, very similar to how I’d felt when I was pregnant with my other two children. But the dates surely didn’t add up?

Convinced the test must be faulty, I booked a private scan, hoping to be reassured.

I wasn’t even looking at the screen when my life changed in seconds as the sonographer announced: ‘Congratulations! You’re 20 weeks pregnant!’
