Gender disappointment

Dont get me wrong Im glad the baby is healthy and doing well but i cried. I waited till we went back to the waiting room and i couldn't hold it in and had to excuse myself to the restroom. This will be our last child and I was really hoping for a boy this time. I know it's God's will for me to have 3 girls but it hurt. Im just praying this feeling wont last long so I can move on and prepare for our little girl. Has anyone dealt with this before? I just feel so bad about feeling sad about it being a girl.
