When I was about 10 weeks pregnant I was very excited to see my doctor, because the pregnancy was advanced enough to be able to hear my baby’s heartbeat on the Doppler. We heard it, and it was unbelievable. It made everything seem real – there was, in fact, a baby on the way. I joked to my practitioner at the time, ‘there’s only one in there, right?’ She laughed and said no way was I having twins, I had barely gained any weight and besides, we could only hear one heartbeat.
