How Long Does Postpartum Bleeding Last, and When Is It Too Heavy?

Postpartum bleeding usually lasts several weeks after birth, starting bright red and heavy and gradually turning pink, brown, then yellowish-white as it tapers. Bleeding that stays heavy, soaks pad after pad, comes with dizziness or fainting, or suddenly gets heavier after it had lightened needs urgent evaluation. This article explains how postpartum bleeding usually changes over time, what counts as too heavy, what can cause it, and what to track at home.

How long does postpartum bleeding last?

After a baby and placenta are delivered, the uterus has a raw area where the placenta was attached. As that area heals, the body sheds blood, mucus and uterine lining through the vagina. This discharge is called lochia. It happens after vaginal births and after cesarean births, although the amount can differ.

For most people, postpartum bleeding continues for several weeks and fades gradually. Some people stop bleeding sooner, and others have light spotting or discharge that comes and goes for longer. Because normal varies from person to person, the pattern over time matters more than any single day. Bleeding that is slowly getting lighter is generally reassuring. Bleeding that stays heavy, gets heavier, or changes character suddenly deserves a call.

MedlinePlus (NIH) describes childbirth problems, including heavy bleeding after delivery, as complications that clinicians watch for in the first days and weeks. That is one reason your delivery team gives you instructions about what to monitor before you go home.

What normal lochia looks like as it changes

Lochia usually moves through color stages. The timing overlaps and varies, so use this table as a general guide rather than a schedule.

Small clots can be part of normal early lochia. Blood tends to pool in the vagina while you lie down or sleep, so you may notice a gush or a few clots when you stand up in the morning. A single episode like that, followed by a return to lighter flow, is common.

Things that can make bleeding look heavier or lighter

Several factors contribute to how much you bleed on a given day, and the mechanisms are not fully understood. These are commonly noticed:

• Activity. Extra time on your feet, lifting, or a long walk can bring on a temporary increase in red flow. Many people see it settle after resting.
• Breastfeeding or pumping. Nursing can cause the uterus to contract, which may cause cramping and a short burst of flow.
• Time of day. Blood that collected overnight can come out all at once on standing.
• Type of delivery. Recovery after cesarean birth has its own features, which are covered in our article on recovery after a C-section.
• Stress, poor sleep and dehydration. These may make you feel worse but do not explain bleeding that is clearly excessive.

An increase after activity that eases with rest is different from bleeding that keeps soaking pads while you are resting.

When postpartum bleeding is too heavy

Heavy bleeding after birth is called postpartum hemorrhage when it is excessive. Clinicians define it by the amount of blood lost together with symptoms of low blood volume, and they manage it in the delivery setting, though it can also appear after you are home. At home, the pattern is what you can recognize.

Bleeding may be too heavy when:

• You are soaking through a pad in an hour or less, and then doing it again and again.
• You pass clots that are large, such as the size of a golf ball or bigger, or you keep passing clots.
• The blood stays bright red and heavy instead of lightening over the days.
• Bleeding lightened or stopped and then became heavier again.
• You feel dizzy, faint, unusually weak, short of breath, or your heart is racing.
• Your skin looks pale or feels cool and clammy.

The symptoms that go with bleeding matter as much as the amount, because they suggest your body is struggling to keep up with the blood loss. Dizziness on standing, fainting, a racing heart, or a cold, clammy feeling together with heavy bleeding is an emergency. Use the 911 list below for these.

MedlinePlus (NIH) lists causes and warning signs of abnormal bleeding on its vaginal bleeding page. That page is written for vaginal bleeding in general rather than after birth, but heavy bleeding with signs of low blood volume still needs prompt medical attention.

Why bleeding can become heavy

There is usually no single cause. Clinicians consider several possibilities, and more than one can be present together:

• The uterus is not contracting firmly enough. After birth, the uterine muscle normally tightens to squeeze blood vessels closed. When it stays soft, bleeding can continue. This is often called uterine atony, and it is one of the common reasons for heavy bleeding after delivery.
• Tissue left behind. A small piece of placenta or membrane can remain in the uterus and keep it from contracting and healing properly. This can cause heavy or returning bleeding days to weeks after birth.
• Tears or injury. Tears of the vagina, cervix or perineum, or a cut from surgery, can bleed. Bleeding from a tear may be steady even when the uterus feels firm.
• Infection of the uterine lining. This can cause heavier or foul-smelling discharge, along with fever and pelvic pain.
• Clotting problems. Some people have an inherited bleeding disorder, such as von Willebrand disease, that they did not know about before. Others take blood thinners. Tell your clinician if either applies, so they can plan your care.
• Conditions of the uterus. Fibroids and other uterine conditions may be associated with heavier bleeding. MedlinePlus (NIH) on uterine diseases gives an overview.

If you are on a blood thinner, or if you have a known bleeding disorder, do not change your dose or timing on your own. Ask the prescriber or your obstetric team what plan is right for you after delivery.

Late or returning bleeding

Some people bleed lightly, then notice a sudden increase days or even weeks later. This is sometimes called secondary or delayed postpartum bleeding. Retained tissue and infection of the uterus are among the possible reasons, and a clinician can examine you and may order an ultrasound or blood tests. Because the cause affects the treatment, it is better to call than to wait and see if a sudden increase continues.

When bleeding is not the only worry

Some dangerous postpartum problems do not announce themselves with bleeding. Knowing them can protect you, because tiredness and a newborn can make everything seem like normal recovery.

• High blood pressure and preeclampsia after birth. Blood pressure problems can develop or continue after delivery. A severe headache that does not ease, vision changes such as spots or blurring, upper abdominal pain, sudden swelling of the face or hands, or a seizure are concerning. MedlinePlus (NIH) describes the condition on its high blood pressure in pregnancy page. A seizure, confusion, a severe headache that does not ease with vision changes, or stroke-like symptoms such as face drooping, arm weakness or trouble speaking call for 911.
• Blood clots. Pregnancy and the weeks after birth are associated with a higher risk of clots. A swollen, painful, warm calf on one side needs same-day medical evaluation; do not wait for a routine appointment. Sudden chest pain, trouble breathing, coughing up blood, or fainting may mean a clot has reached the lungs, which needs 911.
• Infection and sepsis. Fever, chills, a foul-smelling discharge, worsening pelvic or abdominal pain, or a wound that is red, swollen or draining should be assessed the same day. An infection after birth can sometimes spread through the body and become sepsis, which is life-threatening. A high fever with shaking chills, confusion, a very fast heartbeat, or feeling extremely ill needs 911.

What to track and do at home

Simple notes can make a phone call or visit more useful. Many people find it easiest to jot these down on a phone:

• How many pads you use and how full they are, and roughly how long each lasts.
• The color, and whether it is lightening or getting redder.
• The size and number of any clots.
• Any dizziness, headache, fever, pain or odor.

Use pads rather than tampons or menstrual cups during this time, because anything placed in the vagina may raise infection risk while the uterus heals. Ask your clinician before using anything internal and about when it is appropriate to resume sex. Drink fluids, rest when you can, and let others help with lifting and chores. Take any iron or other supplements as your clinician directed, and ask them about anything new.

Keep your follow-up visits. Your clinician can check your blood pressure, your bleeding pattern, and your mood. If sadness, anxiety or hopelessness is growing along with exhaustion, our article on postpartum depression versus the baby blues can help you tell what is going on. Seeing or hearing things that are not there, severe confusion, paranoia, or feeling out of touch with reality after birth can be signs of postpartum psychosis, a psychiatric emergency. Call 911 or go to the emergency room right away, even if you feel safe. Thoughts of harming yourself or your baby also need attention: you can call or text the 988 Suicide and Crisis Lifeline at 988 at any time, and call 911 if you might act on them or cannot keep yourself or your baby safe.

When your period comes back

Lochia is not a period, and it is not triggered by ovulation. A true period can return at different times, and breastfeeding can delay it for some people, though not reliably. The first period after birth can be heavier, longer or more crampy than you are used to. MedlinePlus (NIH) explains normal cycles on its menstruation page. If those periods keep soaking through pads or last unusually long, mention it to your clinician. Because fertility can return before the first period, ask your clinician about contraception options that fit your situation.

Questions to bring to your postpartum visit

• Based on my delivery, how long should I expect bleeding to continue?
• Do I have any risk factors, such as a bleeding disorder, a blood thinner or fibroids, that change what I should watch for?
• Which symptoms should lead me to call you, and which should send me to the emergency room?
• When is it appropriate for me to return to exercise, sex and tampon use?
• Is my blood pressure being checked after I go home?
