how many pads/underwears for post partum

hey ladies I know every woman is different

I did some shopping and ordered a 36 pack of maxi pads and a 19 pack of maximum absorbency Always underwear

is that enough for the bleeding or is the range of bleeding in women so wide I won’t be able to get a close answer?

how long does the underwear usually take to fill?

im scared of this postpartum bleeding time im dreading it 😭😭

how long does the heavy bleeding usually last? and when does bleeding all together usually end?

thanks
