I have two boys and I am now pregnant with number 3. We were told at 20 weeks that it is a little girl and I too have gone a little shopping crazy and I am a little worried that they may have got it wrong. However, my first two pregnancys were identical and this one has been slightly different. My morning sickness lasted longer I have less acid indigestion and less appetite. I do worry though that the differences may just be because i am 3 years older than last time and now have two boys to look after so am permanently shattered. What is your due date? I am due October 17th and I have a scan 4 weeks before that due to a low lying placenta.
