Postpartum hair loss

Tara • First pregnancy, recently engaged, and super excited for everything to come!!
Hi moms! I am pregnant with my first child and have pretty thin hair to start with. I keep hearing horror stories about postpartum hair loss where chunks of hair fall out in the shower, and am kind of worried. Has anyone found a way to minimize hair loss after their baby was born? Or am I just going to be wearing hats for a while. Thanks!!
