What should I be doing and prioritizing in the early weeks of pregnancy?

I’ll ask as bluntly and broadly as possible. I’m sure I’ll be directed to plenty of posts that asked this same question before but wife and I just found out we are pregnant! We’re both very excited and also simultaneously nervous and scared and every other emporium? We are probably around 4-5 weeks along and have our first appointment in a couple of weeks. We haven’t told anyone yet. So, I am coming to the internet. What should we, or more specifically I as the dad, be doing right now? Literally any advice is welcomed. Whether it’s making sure my wife has certain foods, or buying baby stuff, or whatever. What should a first time dad be prioritizing and doing in these early weeks?
