post partum depression?

❤❤Nicole❤❤

I don't feel depressed, I mean when I don't get enough sleep or my baby is having a rough night and is up all night I get sad and sometimes frustrated but once I'm able to take a nap I'm back to myself anyways at my follow up appointment with the questions they asked I guess they rate and score you in a way and I'm told I'm showing signs of post partum depression... can you have it and not realize it or know you have it?
