What should I know about labor & postpartum?

I’m a first time mom & I’m currently in my last trimester. I don’t really have family or friends I can ask about these things? Is there anything I should know or be prepared for? Also I honestly don’t know much about any of this, so “advice for dummies” is probably what I’m aiming for lol. I read stuff on here all the time & literally have know idea what they’re talking about 😬 I feel really unprepared & I don’t even know what to begin to try & look up on the internet. I still have a good 2 months to go so I have some time to educate myself, thankfully 🤣
