In addition to what all the others mentioned, you might want to look into your current health insurance to make sure it covers maternity. Depending on whether you want to go public or private, the pregnancy check-ups, scans, etc. as well as the birth itself can cost a lot of money and it's very difficult to estimate how much it will be in total, so it's definitely recommended to have insurance which covers most, if not all, of it. In my case, for instance, I went private and planned to have a "3-day natural birth" package, but instead I had a "5-day emergency caesarian section" package plus "after normal operating hour" surcharge and ended up paying A LOT more than what I expected. Luckily for me, my insurance paid for everything.
Other than that, try not to worry too much and enjoy this incredible time in your life. Good luck!
