Do i have PND or am I just hormonal

I had my little girl 6 weeks ago and ive recently been feeling really down and upset, I feel like I'm not good enough I never talk about my feelings I feel like my partner doesn't love me even when he tells me I have little to no appetite I can go all day on one meal I don't have thoughts of hurting my kids (I know it says that's a sign) when I'm alone I sit and cry to myself i hate the way i look and it really gets me down i feel depressed all the time but ive never been diagnosed with anything lime that I haven't yet gone the doctors but I'm planning to. Just wondering does this sound like PND?
