Bottom lineWarning signs after childbirth include heavy bleeding, chest pain or breathlessness, a severe headache or vision changes, fever, calf pain or swelling, signs of wound or breast infection, and thoughts of harm - they can appear days or weeks later and need prompt care.

After childbirth, certain symptoms are warning signs that need medical attention. Knowing them helps you act quickly - serious postpartum complications are treatable, especially when caught early.

Urgent warning signs (seek emergency care)

• Heavy bleeding - soaking more than one pad an hour, or large clots
• Chest pain or trouble breathing
• A severe headache that won't ease, or vision changes
• A seizure, fainting, or confusion
• Thoughts of harming yourself or your baby

Call your provider promptly for

• A fever of 38C (100.4F) or higher
• Calf pain, redness, or swelling in one leg

• A wound that's red, swollen, leaking, or opening
• Foul-smelling vaginal discharge, or pain or burning when you pee

Why these matter

These can signal postpartum hemorrhage, infection or sepsis, blood clots, preeclampsia, or postpartum depression - all of which respond well to timely treatment.

A simple rule

If you feel something is seriously wrong, get help. Postpartum warning signs can appear days or weeks after birth, even once you're home, so stay alert during the whole recovery period.
