What are things I need for after birth?

Is there anything I need to be getting in advance for myself for after birth? Or special things I should be packing in hospital bag for me? I know everything baby will need, but what about me? Are there certain kinds of pants, bras, underwear i’ll need? Or will all my regular stuff be fine? Will I need certain kinds of pads or anything for bleeding or care down there? Any kinds of creams, ointments?

I’m a first time mom so I really don’t know what to expect lol
