Depressed pregnant with toddler

Sahm and I’m just feeling so down lately. Want to sleep all day not in the mood for anything but I have a toddler so... there’s that. My husband seems worried so he’s doing everything for me which loads up with all the work he has... I’m just curious to know if this is normal? Maybe hormones? Ever since this pandemic I feel so over it idk 😐 I need a hug.
