Heparin after birth?

M

Hi everyone. Is it standard to get heparin after birth or do they give compression stockings? It’s my first time pregnant almost due and I’m just not aware of what typically happens. I’d like to avoid drugs as much as possible but not very aware of what actually happens. Also paranoid that parts of my placenta will remain in or theyl leave gauze in me (is that only in c section or can it happen with vaginal delivery too?) thanks for the advice!
