Post-partum blues po *hugs! ...dahil po sa hormones at matinding pagod. It usually passes before the 4th trimester ends. Post-partum depression is much more serious and longer, kapag hindi ka na makakilos nang maayos, and/ or you're having "negative" thoughts, etc. but if you're really worried about it, pwede po kayo magpaconsult para mas sure at safe.
