Surprise Quarantine baby! Help 19 and pregnant!

So my boyfriend and I have been together for a while and we were saving up for an apartment together bc we are currently living with my parents in their finished basement. That got old really quickly and we decided that we wanted a place of our own. We both have decent paying jobs and work a lot so it’s not like we couldn’t afford it, so we started looking around for a one bedroom because we didn’t need a ton of space but we didn’t want to feel like we were in a shoebox. So we found this amazing place that literally checks off on everything we were looking for and it’s 825sq ft with a big balcony. So we applied for it and we got accepted (thank you Jesus🙏🏼) and we move in Monday June 15. We are packing everything and we are super busy and I noticed I’ve been having a lot of crazy “pms” symptoms I don’t normally have or at least not to the extent I was experiencing and I was supposed to get my period on the 11th. Well I didn’t so I decided to take a test 👇🏼 and it’s positive as hell all the test lines were darker than the controls. I was in complete shock but very excited. So now I’m just like how are we going to afford this and and pay rent? Please send me all the advice and guidance you guys have because I need it right now. Like what do you actually need to buy when having a baby that’s necessary I don’t want to waste money on what I don’t need when I could be saving it or using it for something else. Also if anyone has any budgeting tips that would be awesome. I’m about 4 weeks and 4 days according to internet calculations.
