In the whirlwind after a baby arrives, everyone watches the newborn — feeding, sleeping, breathing. But the person who just gave birth is also recovering from one of the most demanding events the human body goes through, and serious complications can develop in the days and weeks afterward, sometimes when she is exhausted and not inclined to make a fuss.

That is why partners, family, and new mothers themselves need to know the warning signs. 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 when to act.

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. Postpartum hemorrhage is abnormal, heavy bleeding — most common in the first 24 hours but possible days to weeks later. It is one of the most serious postpartum emergencies.

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

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.

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.

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

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.

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.

A Quick Reference: When to Act

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.
