Surprised by my feelings

My husband and I were both really wanting a baby girl along with the rest of our families who had all been saying the baby is a girl.. found out yesterday that our sweet baby is a boy and my heart sank.. I was caught off guard by my feelings, I cried forever. I already have 2 boys and have been so wanting to do all the fun little girl things. Still get to do all the shopping since my boys are 4yrs and 5 yrs, but I am just surprised at the disappointment I felt when she said the baby is a boy.. has anyone else ever felt that way and how did you cope with it..
