Ppd at 6months pp?

Ga

Okay so I felt great at my 3 and 6 week pp apts where I took the little ppd quiz and I felt great! But for the past few weeks I’ve been not wanting to eat and I’ve lost about 10 lbs and I just cry and cry everyday. Is it possible to get PPD 6w pp?? Or would it be just regular depression? (I was already diagnosed with depression and anxiety 2 years ago)
