How can you tell if you have postpartum Depression?

It’s been almost 4weeks since our angel bear arrived and I’m terribly moody, irritable, extremely tired 24/7, etc.. When should I be concerned about postpartum depression or is it simply just being a new mommy and normal blues??? I’ve read a lot and you see things in ppd about harming yourself or you child and that IS NEVER & WILL NEVER BE A THOUGHT EVER just wanted to point that out.. I just feel so stressed and overwhelmed at times… My finance is so supportive I could not ask for a better guy, but he doesn’t seem to understand why I’m so down and out, he thinks it’s my unhappiness with him and it’s not at all, I’m completely happy, I’m just scared if I don’t “cheer up” its going to cause problems…

i had post-partum depression when my daughter was 1st born till she was like 2 months old and i didnt even realize it till i was asked do i have it..
It doesnt nec. Mean U wanna harm your child..for my case i was always sad..and didnt know why..i never had any energy. I wanted to sleep even after i had a good 8 hours..i never wanted to get dressed or go out ..Never wanted to eat ( i did feed the baby)..

Admitting that you have a problem is nothing to be ashamed of. its not your fault. It doesnt mean your a bad mom or you dont love your child..this is just something that happens and there is Treatment!!!!
you might wanna talk to your OB-GYN…tell her/him what your feeling..they arent gonna think your weird but if i were your OB id think very highly of you that you WANT help ..you dont have to tell your husband ..jus tell your OB…They will give you something..
i wish you and your family the best..
