Don’t know how to feel yet

We already have a daughter and we really want a boy. My husband is the last of his name and we really want a boy to carry the name. I had an awful first pregnancy along with a very traumatic delivery that resulted in a csection. It took us 4 years to decide we wanted another kid. This one will be our last one. I feel like it’s a boy but I’m scared that it will end up being a girl. I really really want a boy aside from having to carry on the name. Don’t get me wrong, I will love my child either way. Just has anyone ever been upset over the gender of their baby?

Edit: well guys. It’s a girl. I’ve cried and cried. But I will love her so much. I guess I just have to wrap my head around it.
