The one-paragraph answer: call 911 or go to the ER now for chest pain, trouble breathing, seizures, thoughts of harming yourself or your baby, bleeding that soaks a pad in an hour, or a severe headache with vision changes.

Call your doctor or midwife today for fever of 100.4°F or higher, an incision that's getting worse instead of better, a painful or swollen leg, worsening bleeding, or feeling sad or hopeless for more than two weeks. When you can't tell which bucket you're in, make the call — any call. Postpartum complications escalate quickly, and "I didn't want to bother anyone" appears in far too many case reviews.

Most pregnancy-related deaths happen not during delivery but in the weeks and months after — and more than 80% are preventable. Prevention usually comes down to one thing: someone recognized a warning sign and acted on it fast. This guide is built on the POST-BIRTH warning signs framework developed by AWHONN (the Association of Women's Health, Obstetric and Neonatal Nurses), organized the way you actually need it — as a decision, not a list.

The decision tree

Start here. Which tier describes you right now?

Tier 1 — Call 911 or go to the ER now

Do not drive yourself. Do not wait to see if it passes. These can be fatal in hours:

• Pain in your chest —  possible blood clot in the lung (pulmonary embolism) or a heart problem.  Pregnancy puts one at a higher risk for blood clots.  

• Trouble breathing, gasping, or shortness of breath at rest

• A seizure — This typically requires immediate attention.  A healthcare provider can assess you for possible eclampsia, even if your blood pressure was normal in pregnancy

• Thoughts of hurting yourself or your baby — call 911 or 988; this is a medical emergency, not a character verdict

• Bleeding that soaks through one pad in an hour, or clots the size of an egg or larger — postpartum hemorrhage can occur up to 12 weeks after birth, not just in the hospital

• Severe headache that won't respond to medication, especially with vision changes (blurriness, spots, light sensitivity), pain in your upper right belly, or sudden swelling of face and hands —  possible postpartum preeclampsia, which most often strikes in the first week after you're home

Tier 2 — Call your doctor or midwife today (if you can't reach them, go to the ER)

Same-day evaluation. Not next week, not at the six-week visit:

• Fever of 100.4°F (38°C) or higher — infection of the uterus, a wound, the breast, or the urinary tract

• A C-section incision or tear that's getting redder, more painful, swollen, or leaking — healing should trend better every day; reversal is the red flag

• One leg that's swollen, red, warm, or painful (especially the calf) — possible deep vein thrombosis, which can become Tier 1 if the clot travels

• Bleeding that had slowed but is getting heavier again, or turns bright red after it had faded

• Pain or burning when you pee, or feeling like you can't empty your bladder

• A hard, red, painful area of the breast with fever or chills — likely mastitis; it's treatable, and you generally don't have to stop nursing

• Feeling sad, hopeless, anxious, or not yourself for more than two weeks — or at any intensity that frightens you. Take a free 3-minute screening right now and bring the result to the call. If sadness comes with thoughts of self-harm, that's Tier 1.

Tier 3 — Mention it at your next visit (and know what would upgrade it)

Uncomfortable, common, and worth discussing — but not urgent on their own:

• Lochia (postpartum bleeding) that's tapering normally over 4–6 weeks → upgrades to Tier 2 if it gets heavier or smells foul

• Night sweats without fever

• Hemorrhoids, constipation, mild incision itching (itching often means healing)

• Baby blues — weepiness and mood swings that peak around day 4–5 and lift within two weeks → upgrades to Tier 2 the day it passes two weeks

• Leaking urine when you sneeze, pain with sex after clearance → common, never "just how it is now"; ask for a pelvic floor referral

• Hair shedding around months 3–4

The overriding rule: these tiers assume a symptom appears alone. Two or more warning signs together, or a gut feeling that something is seriously wrong, moves you up a tier. Mothers who died of preventable causes were often reassured by someone — including themselves — that it was probably nothing. Your instinct about your own body is clinical data.

What to say when you call

You don't need medical vocabulary. This script gets you triaged correctly:

"I gave birth [X weeks] ago. I'm having [symptom] since [when]. It's [getting worse / staying the same]. I [had / didn't have] high blood pressure or a C-section. Do I need to be seen today?"

Two additions that change how seriously you're taken: state your delivery date up front (many ER clinicians don't ask, and postpartum status changes the differential), and if you had any blood pressure problem in pregnancy, say so in the first sentence.

If you're in Pennsylvania on Medical Assistance: the ER visit, the ambulance, and the follow-up are covered — and if getting to a same-day appointment is the obstacle, Medicaid's transportation program will drive you. Cost and logistics should never be the reason a Tier 2 symptom waits a week.

Why the danger window is longer than anyone tells you

The six-week checkup creates a false finish line. In reality: postpartum hemorrhage can occur up to 12 weeks out. Postpartum preeclampsia most commonly appears in the first 7–10 days home — often in women who had no blood pressure problems during pregnancy. Clot risk stays elevated for roughly 6 weeks or more. Postpartum depression and anxiety can begin any time in the first year, with onset frequently after the six-week visit — which is often the last time anyone screens you.

That gap — after discharge, between visits, after the checkup — is exactly where most preventable harm happens. It's also, for what it's worth, the specific problem Phia was built to solve: continuous monitoring of your recovery, 24/7 access to a nurse when you're staring at a symptom at 2am, and same-week mental health follow-up after any positive screen — covered by major Medicaid and commercial plans in PA.

Frequently asked questions

How much postpartum bleeding is too much? Soaking through one pad in an hour, or passing clots egg-sized or larger, is an emergency — go to the ER. Bleeding that had faded and turns heavy or bright red again warrants a same-day call. Normal lochia tapers steadily over 4–6 weeks from red to pink-brown to yellowish-white.

What fever is dangerous after birth? 100.4°F (38°C) or higher means call your provider the same day — it's the standard threshold for suspected infection. Don't pre-treat with ibuprofen and re-check; report the original number.

Can preeclampsia really start after delivery? Yes — postpartum preeclampsia most often develops within the first week after birth and can occur up to six weeks out, including in women with entirely normal pregnancies. Severe headache, vision changes, upper-right belly pain, or sudden face/hand swelling: ER, now.

When is postpartum sadness an emergency? The moment it includes thoughts of harming yourself or your baby — call 911 or call/text 988. Short of that, sadness or anxiety persisting past two weeks deserves a same-day call and a screening, not a wait for the six-week visit.

Should I go to the ER or call my OB first? Tier 1 symptoms: ER, no phone call needed first. Tier 2: call your OB or midwife first, but if you can't reach anyone within a few hours, go in. No one has ever regretted being checked for a postpartum complication that turned out fine.

I don't have an OB or can't reach one. Who do I call? An urgent care or ER can evaluate any of these. If you're in Pennsylvania, Phia patients can reach a licensed clinician 24/7 — check your eligibility. For emotional crises: 988, or the National Maternal Mental Health Hotline at 1-833-852-6262 (24/7, free).
