Things I don't know about giving birth

Cali☀️
Can someone please give me a list of things I don't know about giving birth. I'm a ftm due in August. I heard you poop when you give birth, you get sewn up after (does it hurt?), and you bleed for days and have to wear a pad. Just would like to know what to expect so if anyone can give me a list of things, that would be great! Thanks!
