Bottom linePostpartum bleeding is an emergency when you soak more than a pad an hour, pass clots bigger than a golf ball, or feel faint, dizzy, or short of breath - signs of postpartum hemorrhage, which can occur up to 12 weeks after birth; call emergency services.

Postpartum bleeding is an emergency when it's very heavy, comes with large clots, or makes you feel faint or unwell. Soaking more than one pad an hour, or passing clots bigger than a golf ball, can be a sign of postpartum hemorrhage - call emergency services.

Treat it as an emergency if you have

• Bleeding that soaks more than one pad an hour, or doesn't slow down
• Clots bigger than a golf ball, or several large clots
• Bright red, heavy bleeding that returns after it had settled
• Feeling faint, dizzy, weak, or short of breath
• A racing heart, or pale, clammy skin

Call emergency services or go to the ER right away - these can signal postpartum hemorrhage, which is a medical emergency.

Important timing

Postpartum hemorrhage can happen in the first 24 hours but also up to 12 weeks after birth (secondary hemorrhage), often from a retained piece of placenta or infection. So heavy bleeding weeks later is still an emergency.

Call your provider promptly (not always 999) for

Bleeding that's heavier than expected but not torrential, foul-smelling discharge, or a fever - these still need prompt assessment.

Don't wait

If you're losing a lot of blood or feel unwell, don't try to ride it out. Quick treatment is highly effective.

Femora helps you track pad changes and flow so you can recognize when bleeding crosses into emergency territory.
