Quick Answer

Call 911 for a new mother who has heavy bleeding (soaking a pad an hour or passing clots larger than a golf ball), signs of shock (dizziness, fainting, racing heart, pale clammy skin), chest pain or sudden shortness of breath, a severe headache with vision changes, a seizure, a very high fever with severe pain or confusion, or thoughts of harming herself or the baby.

Call the doctor or midwife the same day for a low-grade fever, foul-smelling discharge, a painful red wound or breast, calf pain or swelling, or persistent low mood — anything that feels “off” but is not immediately dangerous. When in doubt, make the call: providers would always rather be contacted early.

Guidelines this article follows: recognition and triage guidance aligned with the Canadian Red Cross and Heart & Stroke Foundation of Canada first aid programs, the Society of Obstetricians and Gynaecologists of Canada (SOGC), and the International Liaison Committee on Resuscitation (ILCOR) 2025 consensus on postpartum hemorrhage first aid. This is educational information, not a substitute for care from your doctor or midwife.

So much attention goes to the new baby that the person who just gave birth can be overlooked — yet they are recovering from one of the most demanding events the human body goes through, and serious complications can develop in the days and weeks afterward. Many of the most dangerous postpartum complications are very treatable when caught early, and easy to miss when everyone’s focus is on the baby. This guide covers what to watch for and exactly when to act.

This article is about recognizing warning signs, not diagnosing or treating. When in doubt, call your doctor, midwife, or 911. New parents are often reluctant to “bother” anyone — but healthcare providers would always rather be called for something minor than have a serious complication missed.

Why the First Weeks Matter

The postpartum period — generally the first six weeks, though some risks extend longer — is a time of major physical change. Blood volume shifts, the uterus contracts back down, wounds (whether a C-section incision or a vaginal tear) heal, and hormones swing dramatically. Most of this is normal recovery. But a handful of complications are genuine emergencies, and knowing them turns a worried partner into a prepared one.

Postpartum Hemorrhage (Heavy Bleeding)

Some bleeding after birth is normal and gradually lightens over weeks — a blood loss of up to about 500 ml at a normal delivery is expected. Postpartum hemorrhage is abnormal, heavy bleeding beyond that; it is most common in the first 24 hours but possible days to weeks later, and because the uterus’s blood flow is so great it can bleed fast enough to be life-threatening. It is one of the leading causes of maternal death worldwide and one of the most serious postpartum emergencies.

Source: ILCOR 2025 CoSTR (postpartum hemorrhage first aid); St. John Ambulance / SOGC — normal blood loss up to ~500 ml, beyond which counts as hemorrhage.

Watch for:

Soaking through more than one pad an hour
Passing blood clots larger than a golf ball
Bleeding that gets heavier rather than lighter, or suddenly increases
Signs of shock: dizziness, faintness, weakness, a racing heart, pale or clammy skin, blurred vision

Heavy postpartum bleeding is a 911 emergency. While waiting for help, have her lie down and keep her warm. If she is alert, encourage the baby to breastfeed and gently rub the lower abdomen — nursing and external uterine massage both help the uterus contract and can slow the bleeding (ILCOR 2025). Never place anything inside the vagina. If she becomes unresponsive and is not breathing normally, begin CPR and follow the 911 dispatcher’s instructions — a skill worth having before baby arrives.

Source: ILCOR 2025 CoSTR — external uterine massage (including self-massage) and breastfeeding are suggested first-aid measures to help prevent and treat postpartum hemorrhage.

Blood Clots (DVT and Pulmonary Embolism)

New mothers have a significantly increased risk of blood clots for several weeks after birth, because pregnancy changes how the blood clots and mobility is often reduced.

Clot in the leg (deep vein thrombosis)

Watch for pain, tenderness, warmth, redness, or swelling — usually in one calf or thigh. This needs urgent medical attention to prevent the clot from travelling.

Clot in the lungs (pulmonary embolism) — life-threatening

If a clot travels to the lungs, it is an emergency. Watch for sudden shortness of breath, chest pain that worsens when breathing in, a rapid heartbeat, lightheadedness, or coughing up blood.

Call 911 immediately for any signs of a lung clot. Contact a doctor urgently for signs of a leg clot.

Source: Heart & Stroke Foundation of Canada; SOGC — venous thromboembolism (DVT/PE) risk is elevated for up to about six weeks postpartum.

Infection

Infections can develop in the uterus, a C-section incision, a tear, the breasts (mastitis), or the urinary tract. Watch for:

Fever (generally 38°C / 100.4°F or higher)
Foul-smelling vaginal discharge
A C-section or tear wound that is increasingly red, swollen, warm, painful, or leaking pus
Severe abdominal or pelvic pain
A red, hot, painful area on the breast with flu-like symptoms (possible mastitis)
Pain or burning with urination

Contact the doctor or midwife the same day for these. A high fever with severe pain, confusion, or feeling very unwell warrants emergency care, as infection can become serious quickly.

Source: SOGC; Canadian Red Cross first aid guidance — a temperature of 38°C / 100.4°F or higher is the usual threshold for a fever warranting review.

Postpartum Preeclampsia and High Blood Pressure

Preeclampsia — dangerously high blood pressure — can develop after birth, even if blood pressure was normal during pregnancy. It usually appears in the first days to weeks postpartum. Watch for:

A severe headache that doesn’t ease with rest or medication
Vision changes — blurring, seeing spots or flashing lights
Pain in the upper abdomen, often under the ribs on the right side
Sudden swelling of the face or hands
Nausea or vomiting, shortness of breath, or sudden weight gain

Seek urgent medical care for these symptoms. Call 911 for severe symptoms or if she has a seizure — untreated preeclampsia can progress to seizures (eclampsia), a life-threatening emergency. See our seizure first aid guide.

Source: SOGC (Hypertensive Disorders of Pregnancy guideline) — postpartum preeclampsia can occur up to about six weeks after delivery.

Postpartum Mental Health

Recovery is not only physical. The “baby blues” — mood swings, tearfulness, and overwhelm in the first couple of weeks — are common and usually pass. But postpartum depression and anxiety are real medical conditions that can develop in the weeks and months after birth, and they deserve the same attention as any other complication.

Partners should gently watch for persistent sadness, hopelessness, severe anxiety, inability to sleep even when the baby sleeps, withdrawal, difficulty bonding with the baby, or feeling unable to cope. These are treatable, and reaching out for support is a sign of strength, not failure.

This is an emergency: If a new mother expresses thoughts of harming herself or the baby, has frightening or intrusive thoughts she can’t control, or seems detached from reality, seek help immediately — call 911 or a crisis line, and do not leave her alone. Postpartum psychosis is rare but a true medical emergency.

Source: Public Health Agency of Canada; SOGC — postpartum depression, anxiety, and (rarely) postpartum psychosis are recognized perinatal mental health conditions.

If you or someone you love is struggling, this is a sensitive and important topic — reaching out to a doctor, midwife, or a trusted person is the right first step, and help is available. In Canada, the 9-8-8 Suicide Crisis Helpline is available 24/7 by call or text.

A Quick Reference: When to Act

Call 911 or go to the ER for:

Heavy bleeding (soaking a pad an hour, golf-ball clots), signs of shock, chest pain or sudden shortness of breath, a severe headache with vision changes, a seizure, a very high fever with severe pain or confusion, or thoughts of harming herself or the baby.

Call the doctor or midwife the same day for:

A low-grade fever, foul-smelling discharge, a painful red wound or breast, calf pain or swelling, persistent low mood or anxiety, or anything that feels “off” but not immediately dangerous.

For Partners: You Are Part of the Recovery Team

As a partner, you may be the one who notices that something isn’t right when the new mom is too exhausted to advocate for herself. Take the warning signs seriously, keep emergency numbers handy, encourage rest and hydration, help track bleeding and symptoms, and never hesitate to call for help. Knowing CPR and basic emergency response means that in the rare worst case, you can act in the critical first minutes.

Prepare Together Before Baby Arrives

The best time to learn this is before the baby comes, when you have time and focus. A Life Safe first aid and CPR course — ideally taken together in the third trimester — equips partners with CPR and emergency response skills for both mom and baby, so your household is ready for whatever the postpartum weeks bring.

What are the warning signs of postpartum hemorrhage?

Soaking through more than one pad an hour, passing clots larger than a golf ball, bleeding that gets heavier rather than lighter, dizziness or faintness, a racing heart, pale or clammy skin, and blurred vision. It can occur in the hours after birth but also days to weeks later. It’s a medical emergency — call 911 for heavy bleeding or signs of shock.

What are the signs of a blood clot after giving birth?

New mothers have higher clot risk for weeks after birth. A leg clot causes pain, tenderness, warmth, redness, or swelling, usually in one calf or thigh. A lung clot is life-threatening: sudden shortness of breath, chest pain worsening with breathing, rapid heartbeat, or coughing up blood. Call 911 for lung-clot signs; contact a doctor urgently for leg-clot signs.

Can you get preeclampsia after giving birth?

Yes. Postpartum preeclampsia can develop in the days and weeks after delivery, even if blood pressure was normal in pregnancy. Signs include a severe persistent headache, vision changes, upper abdominal pain, sudden facial or hand swelling, nausea, and shortness of breath. Seek urgent care, and call 911 for severe symptoms or a seizure.

When should a new mom go to the hospital after birth?

Call 911 or go to the ER for heavy bleeding, signs of shock, chest pain or sudden shortness of breath, a severe headache with vision changes, a high fever, a seizure, thoughts of harming herself or the baby, or any sudden severe symptom. For milder concerns like a low-grade fever, foul-smelling discharge, or a painful red area, contact the doctor or midwife the same day.

Protect Mom and Baby in the Fourth Trimester

The weeks after birth deserve the same readiness as the delivery itself. Life Safe’s hands-on first aid and CPR courses prepare partners and families to recognize emergencies and act fast — for the new mother and the newborn alike.
