Hair loss

I can’t find a postpartum community but i wanted to ask is there anyway you can prevent the hair loss, and when you say hair loss do you mean shedding or actual clumps of hair. i’m so nervous for everything in a first time boy mom and life has already been kicking my ass. but for some reason at 32 weeks and 6 days today i decided to tell my bf to cut my hair my hair was like mid breast length and grew a lot more during the pregnancy but idk it felt lifeless and so thin that i could see through it and my split ends were so ugly making all kinds of letters in the alphabet. so i big chopped and i just realized the ppd hair loss was like a thing how can i prevent this im so scared.

i am 23 and my hair is natural 3c/4a fine low density hair
