depression

Aspen • Expecting mommy to twins👶🏻👶🏻 married for 3 years to my amazing husband.
I'm 11w pregnant tomorrow with my precious twins. My husband is thrilled and has been helping me through everything but I've been super depressed and nervous. My mom said she never felt depressed is it normal to feel this way this soon? I still work and live a normal day to day life but can't shake this depression.
