We know PPD has real, documented risk factors:
-- Personal or family history of depression or mood disorders
-- Depression or anxiety during pregnancy
-- Poor or limited social support
-- Intimate partner violence or relationship stress
-- Sleep disorders
-- Unintended pregnancy
-- Stressful life events
-- History of trauma or abuse
-- Difficult delivery or pregnancy complications
-- Low sense of confidence in your parenting abilities
But new research published in Neuropsychopharmacology adds something significant to that picture: specific hormone ratios in the third trimester — measurable before any symptoms appear — can predict who is likely to develop PPD.
The research points to an imbalance in how some people process progesterone late in pregnancy, creating a biological vulnerability to the hormonal crash that happens after birth. In other words, for some people, the groundwork for PPD is laid months before delivery — not because of anything they did or didn't do, but because of how their brain and body are processing hormones during pregnancy.
Knowing your risk — whether it's circumstantial, historical, or biological — means you can start building support before your baby arrives, not in the middle of a crisis.
That's exactly the kind of work we do in perinatal mental health: helping you understand your history, your risk factors, and what proactive support can look like for you specifically. Whether that's processing a previous perinatal experience, working through anxiety during pregnancy, or simply having a therapist in your corner before your due date, there is no wrong time to start.
