ppd ?

hey mamas, had my son december 30th and since this morning i’ve been feeling off, when people talk to me i don’t want to open my mouth to answer, i don’t care to speak to my family, i don’t want anyone toutcing my baby and everything is making me either irritated or wanting to cry .. are these signs of ppd? i think i had it with my first and never noticed until i was on a drinking binge every minute my bd had him .. i don’t want to let it go untreated if it could be ..
