Is it ppd ?

Has anyone experienced postpartum depression that sort of comes in waves ? I’ll have some consecutive good days , then inevitably like a week or two where I just want to crawl in a hole.

It’s not like I cry nonstop or even that much. I mostly feel very unmotivated, exhausted and extremely disconnected from people , esp my husband (which is crazy cuz he’s the sweetest , best person).

Is it ppd or something else ? Is it just normal postpartum hormones ?
