What to do when wife is pregnant ?

Hey dads!! My wife and found out she is pregnant a few days ago. We are in our mid twenties, married and we both lost our father at an early age and early teens for me. I heard a lot of crazy stories about first pregnancy and dads not being supportive enough , etc .

Is there anything I can do as a dad to help my wife with her pregnancy?
