Can it still be PPD/PPA if it’s months later?

Hi all long time lurker but don’t really post. I’m 7 almost 8 months PP and I’ve had a relatively easy last 7 months with a wonderful little baby. Slept in their crib from day one until 6 months when we transitioned to the cot, they hated it and now we safely co sleep. Baby has an egg allergy which was found quite early into starting weaning so testing allergies was advised against until we have the allergy testing, so weaning has felt restrictive. Im here more for this one question, can you still have PPD/PPA but come months later? my birth was incredibly traumatic and I’ve slowly started to process the reality of what happened, and I’ve become incredibly anxious to leave the house, drive anywhere and just feel sad a lot of the weeks, but this is all new and only since the return of my period 6 months PP. before that everything was okay. not sure what to do, if the GP would help at all or if it’s just a phase of life in motherhood I need to fester through.
