I can totally relate to this.
I've only got one child, a son (I'm pregnant with number 2) and it feels wrong to have suffered GD with my first baby but my Nan had not long died and I was desperate to carry her name on, I just longed for a girl for so many reason and hated finding out it was a boy. This time I'm less worried but I still feel that stab of pain every time someone announces they are having a girl.
And just to make matters worse, my best friend is pregnant, only 5 days behind me! And she is having a gender scan same day as me and she wants a boy but I can bet she has a girl and I have a boy, it would just be typical. I'm dreading finding out the sex this time but don't feel as worried as I've convinced myself I won't be having a girl anyway!
