Postpartum Hemorrhage Symptoms: Early Warning Signs You Should Know

What you will learn about postpartum haemorrhage in this guide:

• Postpartum hemorrhage (PPH) is defined as losing more than 500 mL of blood after a vaginal birth or more than 1,000 mL after a C-section.
• Common postpartum haemorrhage symptoms include large blood clots, severe abdominal pain, dizziness or fainting, a rapid heartbeat, pale or clammy skin, and shortness of breath.
• Postpartum haemorrhage usually occurs within the first 24 hours of childbirth, but it can also develop up to 12 weeks after delivery.
• The most common cause of postpartum haemorrhage (PPH) is uterine atony, which occurs when the uterus doesn’t contract strongly enough after childbirth.
• Postpartum haemorrhage can often be prevented or significantly reduced through standardized medical protocols, including Active Management of the Third Stage of Labour (AMTSL).

 Postpartum haemorrhage (PPH) is a condition that causes excessive bleeding after childbirth and requires prompt medical attention. While some bleeding after delivery is a normal part of healing, it’s important to know when it may be a sign of something more serious. Understanding the postpartum haemorrhage symptoms can help you tell the difference between a normal part of postpartum recovery and a situation that needs urgent care.

In this guide, we’ll walk you through the most common postpartum haemorrhage symptoms, when PPH can occur, its causes, risk factors, prevention strategies, and what to do if something doesn’t feel quite right.

How is PPH different from normal postpartum bleeding?

Postpartum haemorrhage (PPH) is severe bleeding after childbirth. Now, some bleeding after delivery is completely normal. Your body has just done something incredible, after all. But if you’re soaking through a maternity pad in less than an hour or finding yourself making far too many trips to change it, it could be a sign of postpartum hemorrhage. 

In medical terms, PPH is defined as losing more than 500 mL of blood after a vaginal birth or more than 1,000 mL after a C-section.

But postpartum hemorrhage isn’t just about what’s happening in your maternity pad. When your body loses a large amount of blood in a short time, your blood pressure can drop suddenly. This means less blood reaches important organs like your heart and brain. In severe cases, this can lead to hypovolemic shock, a life-threatening condition that requires immediate medical attention.

While some bleeding after birth is expected, knowing when it crosses the line from normal to excessive can help you get the care you need, when you need it most. 

 Other Symptoms of Postpartum Hemorrhage

• Large blood clots: While small clots can be normal, passing clots larger than a golf ball size aren’t considered part of a typical recovery. (Read more about postpartum clots here.)
• Severe abdominal pain: More intense than the usual post-birth cramps and aches.
• Dizziness or fainting: Feeling weak, lightheaded, or like the room is spinning.
• Rapid heartbeat: Your heart may start working overtime to make up for blood loss.
• Pale, cold, or clammy skin: Another sign that your body needs urgent attention.
• Shortness of breath: Feeling unusually breathless, even while resting.

Not all postpartum bleeding is a sign of postpartum haemorrhage, but recovery can still be messy, unpredictable, and heavier than you might expect. That’s where the right support can make all the difference.

Nua’s Maternity Pads are designed with front-to-back coverage to help you stay comfortable and protected through every stage of postpartum recovery. Built to absorb heavy flow, gushes, and clots, they let you focus on what matters most—healing, resting, and bonding with your baby.

When does postpartum haemorrhage occur? 

Postpartum haemorrhage (PPH) usually occurs within the first 24 hours after childbirth, but it doesn’t always follow a strict schedule. In some cases, it can occur up to 12 weeks after delivery, long after you’ve settled into life with your newborn.

When heavy bleeding after delivery occurs within the first 24 hours of birth, it’s known as primary postpartum haemorrhage. If the bleeding develops between 24 hours and 12 weeks after childbirth, it’s called secondary postpartum haemorrhage.

Postpartum recovery isn’t just about caring for your newborn. Between feeding schedules, diaper changes, and trying to squeeze in a little sleep, it’s equally important to check in with your own body and pay attention to any unusual symptoms.

And while PPH is treatable, it should never be taken lightly. Severe bleeding after childbirth remains one of the leading causes of maternal deaths worldwide. According to the World Health Organization (WHO), postpartum haemorrhage affects millions of women every year and contributes to around 70,000 maternal deaths globally. Knowing the warning signs and seeking medical help early can make all the difference.

What causes PPH? 

The most common cause of postpartum haemorrhage (PPH) is uterine atony, which occurs when the uterus doesn’t contract strongly enough after childbirth.

Once your baby is born, your uterus gets straight to work, gradually shrinking back to its pre-pregnancy size. As this happens, the placenta separates from the uterine wall. The area where the placenta was attached contains many blood vessels, so some postpartum bleeding is completely normal. This is why lochia (the vaginal discharge after childbirth) is often heavier than a typical period in the first few days. (Read more about it here.)

It’s important to remember that heavy postpartum bleeding and postpartum haemorrhage aren’t the same thing. The difference lies in the amount of blood loss and how your body responds to it. 

Healthcare providers often group the causes of postpartum haemorrhage into the Four Ts: Tone, Trauma, Tissue, and Thrombin.

1. Tone (Uterine Atony): Think of the uterus as nature’s built-in pressure bandage. After birth, it needs to squeeze down firmly to help close off the blood vessels left behind by the placenta. If those muscles stay too relaxed, bleeding can continue. 
2. Trauma: Childbirth can sometimes cause tears or injuries to the vagina, cervix, uterus, or perineum. Even when they’re not immediately obvious, these injuries can continue to bleed after delivery.
3. Tissue: Sometimes, a small piece of the placenta remains attached to the uterine wall. When the uterus senses that something is still there, it may struggle to contract properly, increasing the risk of postpartum haemorrhage.
4. Thrombin: This refers to blood-clotting problems. If your blood isn’t clotting the way it should—whether due to an existing condition or a pregnancy-related complication—even a small bleed can become more significant.

Nua’s Maternity Pads provide reliable protection, helping you stay comfortable and confident as your body heals. 

What Should I Do If I Think I Am Experiencing Postpartum Haemorrhage?

If you experience heavy bleeding after childbirth, especially if it’s accompanied by fatigue, large blood clots, dizziness, or fainting, seek emergency medical care immediately. Postpartum haemorrhage can become serious very quickly, so it’s important not to wait and see if it improves on its own.

While you’re waiting for medical help:

• Lie down and elevate your legs slightly to help maintain blood flow to your brain.
• Have someone stay with you and monitor your breathing and alertness.
• Avoid standing up or walking around, as blood loss can make you feel dizzy or faint.

Can postpartum haemorrhage be prevented? 

Yes, postpartum haemorrhage (PPH) can often be prevented—or at least significantly reduced—with the right care and timely intervention. While it can sometimes happen unexpectedly, healthcare providers have several proven ways to lower the risk of excessive bleeding after childbirth.

One of the most effective approaches is Active Management of the Third Stage of Labour (AMTSL), which is a set of steps taken right after your baby is born to help your uterus contract properly and support a smoother recovery.

These measures may include:

• Uterotonic Medications: Medicines such as oxytocin, carbetocin, or misoprostol help the uterus contract and reduce the risk of excessive bleeding.
• Controlled Cord Traction: Your healthcare provider may gently guide the placenta out to help minimise blood loss.
• Uterine Massage: A gentle massage encourages the uterus to shrink and close off blood vessels after delivery.
• Treating Anaemia During Pregnancy: Healthy iron levels can help your body better cope with blood loss.
• Early Detection and Accurate Measurement: Special tools help healthcare teams identify and treat postpartum haemorrhage as early as possible.

The good news? While postpartum haemorrhage can sound scary, it’s often preventable, recognizable, and treatable with prompt medical care.

Who is more likely to have postpartum haemorrhage? 

Postpartum haemorrhage (PPH) can happen to anyone after childbirth. In fact, it can occur even in women with no underlying health conditions or previous history of pregnancy complications.

Some factors that may increase the risk include:

• A previous experience with postpartum haemorrhage or blood-clotting disorders such as von Willebrand disease.
• A long or induced labour, or an episiotomy (a small cut sometimes made to help with delivery).
• Certain pregnancy conditions, such as carrying twins or triplets, preeclampsia (high blood pressure during pregnancy), placental abruption (when the placenta separates from the uterus before birth), or uterine fibroids.
• Certain types of delivery, including a C-section or a vacuum- or forceps-assisted birth.
• Being over the age of 35.
• Obesity or a higher body mass index (BMI).
• Medical conditions such as high blood pressure or diabetes.

Before you start mentally checking boxes, remember this: having one or more risk factors doesn’t mean you’ll experience postpartum haemorrhage. And not having any doesn’t guarantee you’ll avoid it. These factors simply help your healthcare team know when to keep a closer eye on things and provide the right support for a safer postpartum recovery.

Final Takeaway

While postpartum haemorrhage (PPH) can be a serious complication of childbirth, it is also one that healthcare providers are trained to recognize and treat quickly. Knowing the difference between normal postpartum bleeding and the warning signs of postpartum haemorrhage can help you seek care when it matters most.

Remember that postpartum recovery isn’t just about caring for your baby—it’s about caring for yourself, too. If something feels unusually heavy, sudden, or concerning, trust your instincts and reach out to a healthcare provider. 

And while you’re focusing on recovery, don’t forget about your comfort. Nua’s Maternity Pads are designed to provide soft, secure protection during the postpartum period, helping you feel supported through every step of your healing journey.
