Carrying low

Brittany
So my fiancé and I were told we were having a girl took 2 nurses then a doctor who said he saw 3 lines.. Which made us nervous that it isn't and we really want a girl.. Now being 30 weeks, I am carrying low, only gained in the front and worried that after so much prep for a girl that we may be surprised the day of labor.. Either way I'm happy with a healthy baby but I had fingers crossed for a girl ... Thoughts?
