My Wife is pregnant

Hello everyone.
So I am 22 and my wife is 22. We just found out yesterday that she is pregnant and we couldn’t be happier. We both have always wanted to become parents and wanted to do it pretty young so we could grow up with each other and our children.
I currently make about 57k a year and she makes about 50k. We will be going down to just my income when she has the baby. So I am stressing a little about that. Any advice for a first time father?
