Gender Disappointment

I haven't found out yet but I was wondering if there's any other ladies who've experienced this. My fiancé and I are both hoping for a girl. Actually everything is planned for a girl and nothing is planned for a boy. I mainly want a healthy easy pregnancy and delivery followed by a healthy smart baby but I do feel pressure of it must be a girl. My fiancé lost his daughter and has 2 sons and I just feel like I must give him a girl.
