Anxious

My ultrasound to found out the baby's sex is next week and I can't stop thinking about it.  I have all the symptoms to be having a boy (I'm hairy, want to easy sour and salty food...) but my doctor thinks is a girl because on my last ultrasound the baby's heart beat was 164bpm, which usually that's a sound of a baby girl. So I'm confused. Arg! Any ideas??
