Postpartum hair loss?

Wifey • Mama of 1 ... ttc #2 Rainbow Baby with secondary infertility.
My LO is 5 months and I'm having major hair loss. Like...clumps in the shower! I have heard that it's normal after giving birth due to a change in hormones but I seriously feel like I'm going to go bald at this rate!! 
Is there anything I should do??
