Passing small blood clots in the first days after giving birth is a normal part of how the body heals. The place where the placenta was attached leaves a raw area inside the womb, and it has to bleed, clot and close over several weeks.1Dr ME Ghodhbani. The Biological Recovery Process After Placenta Delivery What separates normal from worrying is less whether you see clots and more their size, how often they come, and whether the bleeding is easing or getting worse over time.
When a Clot Is a Warning Sign
Any one of these is a reason to get help right away:
- Clots larger than an egg.2Northside/Northpoint OB-GYN. Postpartum Warning Signs to Call a Doctor
- Soaking through a pad in one hour or less.3Nationwide Children’s Hospital. Postpartum Hemorrhage
- A sudden increase in bleeding after it had started to slow down.4Northside/Northpoint OB-GYN. Postpartum Warning Signs to Call a Doctor
- Passing a lot of blood together with pieces of tissue.5Raveco Medical. When Ovarian Cysts Resolve—and When to Seek Care
Compare a clot to a hen’s egg or a golf ball; anything that size or larger counts. A soaked pad means the whole pad is heavy and wet, not just a spot in the middle. Note the time when you put on a fresh pad so you know whether an hour has passed.
Size is only part of the picture. Several smaller clots passed one after another can add up to the same worry, and clots that keep coming with each trip to the toilet, rather than one clot that then stops, suggest the womb is still filling with blood. Small clots, about the size of a coin or a grape, passed in the first days are not by themselves on this list.
Your body also gives signals. Feeling lightheaded, dizzy or faint is a reason to seek immediate care.6Nationwide Children’s Hospital. Postpartum Hemorrhage So are a fast heartbeat, blurry vision, extreme tiredness, or belly pain that is new or getting worse.7Nationwide Children’s Hospital. Postpartum Hemorrhage These can signal postpartum hemorrhage, heavy bleeding that can drop blood pressure and lead to shock if untreated.8Raveco Medical. When Ovarian Cysts Resolve—and When to Seek Care If any of them happen, call your doctor or go to emergency care rather than waiting to see if it settles.
Symptoms can show up before the bleeding looks dramatic, because some blood collects inside the womb and never reaches the pad. Feeling faint when you sit or stand, or a heart that pounds while you rest, deserves a call rather than being put down to tiredness.
In the moment, lie down if you feel faint, and don’t drive yourself if you are dizzy. Call your maternity unit, doctor or emergency number and say how many pads you have soaked and how large the clots are. If you can, keep the soaked pad or clot to show staff, or take a photo. If you have been shown how, massaging the lower belly firmly can help the womb tighten while you wait.
How Bleeding and Clots Change Over the Weeks
The bleeding after birth is called lochia, and you may see that word on hospital leaflets.9Raleigh-OBGYN. Understanding Postpartum Bleeding: What’s Normal and When to Seek Help It is a mix of blood, shed womb lining, mucus and bacteria, so not all of it is pure blood.10The Vulva. Characterization and treatment of lochia
For about the first 3 to 4 days the bleeding is bright red and heavy, like a heavy period, and this is when clots are most common.11Raleigh-OBGYN. Understanding Postpartum Bleeding: What’s Normal and When to Seek Help From about day 4 to day 10 it turns pinkish or brownish and lighter, with less tissue passing.12Raleigh-OBGYN. Understanding Postpartum Bleeding: What’s Normal and When to Seek Help From around day 10 it becomes white to pale yellow and can continue for up to six weeks.13Raleigh-OBGYN. Understanding Postpartum Bleeding: What’s Normal and When to Seek Help Some women have light discharge for longer, up to about 10 weeks.14MamasteFit. Passing Blood Clots After Birth: What Is Normal? The overall direction matters more than the exact day: lighter and paler over time is the healthy pattern.
Within that fade, small ups and downs are normal. After the bleeding has turned pink-brown or pale yellow, a day of extra walking, lifting or stairs can bring back a flush of red, and this often settles after resting. Red that stays or keeps getting heavier needs a call, as does a return of heavy bright red bleeding with clots after lighter days, even if you are not soaking a pad every hour. A bad smell or a fever alongside returning red points toward infection and is a reason to call the same day.
Lochia happens after a cesarean too, because the placenta site has to heal either way. The same stages and warning signs apply after either kind of birth.
Use maternity pads throughout, not tampons or menstrual cups. The womb opening is still soft and the placenta site is healing, and anything inserted raises the risk of infection. The first few days may call for a thick overnight-style pad, then a thinner one as bleeding eases. Noting each pad’s color and any clots, even in a phone note, shows whether the trend is lighter and paler and lets you tell a midwife or doctor exactly what has changed.
Why Clots Appear When You Stand Up
Bleeding can seem heavier in the morning or after lying down, because blood pools in the vagina and is passed when you stand.15University Hospital Southampton NHS Foundation Trust. Blood loss – what to expect after the birth of your baby So small clots when you first get up are typical in the early days.16withpower.com. Understanding Blood Clots After Birth
Sitting for a long stretch, such as through a long feed or in the car, can have the same effect as lying down. Clots from pooling are often dark red because the blood has sat for a while.
The clots themselves come from the placenta site. The womb tightens and clamps the blood vessels where the placenta was attached, and the body’s clotting system seals them as part of healing. Some of that clotted blood is shed in the early days, which is why small clots are expected.
To tell a pooling gush from a real increase, see whether the flow slows within minutes of the first rush. Change your pad and check again over the next hour. Steady soaking after the gush points to ongoing heavy bleeding, not pooling. If the gush comes with dizziness, a pounding heart or a clot bigger than an egg, treat it as a warning sign.
Breastfeeding and Cramping After Birth
When your baby suckles, your body releases the hormone oxytocin.17Nursing & Primary Care. Effect of Early Initiation of Breastfeeding on the Uterine Consistency and the Amount of Vaginal Blood Loss during Early Postpartum Period Oxytocin makes the womb contract, which can bring cramps and push out pooled blood.18Nursing & Primary Care. Effect of Early Initiation of Breastfeeding on the Uterine Consistency and the Amount of Vaginal Blood Loss during Early Postpartum Period That also means breastfeeding helps the womb return to its pre-pregnancy size faster.19Nursing & Primary Care. Effect of Early Initiation of Breastfeeding on the Uterine Consistency and the Amount of Vaginal Blood Loss during Early Postpartum Period
These cramps, called afterpains, often feel like period cramps during or just after feeds. They are often stronger after a second or later baby. They usually come in waves when the baby latches and ease within a few minutes, unlike steady pain that never lets up. Emptying your bladder before feeding helps the womb contract, and your provider can tell you which pain reliever is safe while breastfeeding.
A small clot during a feed is expected, but soaking a pad during feeds is not. Afterpains usually fade over the first several days as the womb shrinks, so cramping that builds rather than fades, constant cramping or severe belly pain needs checking.
What Causes Abnormally Large Clots or Heavy Bleeding
The most common cause is the womb muscle not contracting enough after birth.20Osmosis. Uterine Atony Blood collects inside the womb and comes out as heavy bleeding or large clots.21Osmosis. Uterine Atony A womb that isn’t tightening feels soft and large rather than firm, which is what staff check when they press your belly.22Osmosis. Uterine Atony Women who needed a lot of oxytocin through a drip during labor are more likely to have severe bleeding from this.23PubMed Central. Oxytocin exposure in women with postpartum hemorrhage secondary to uterine atony
Pieces of placenta left in the womb can keep it from closing down and cause bleeding.24PubMed. Management of post-partum haemorrhage Infection or inflammation of the womb lining can also cause abnormal bleeding after birth.25Journal of Urgent Care Medicine. Postpartum Presentations: When Risk Arises After Delivery – Vaginal Bleeding and Discharge Leftover tissue often shows up as bleeding that keeps going, comes back after slowing, or brings clots well past the first week. Infection usually brings lower belly tenderness, a bad-smelling discharge and often fever or chills, so bleeding that smells bad or comes with fever and pain should be checked promptly. Both can be treated, with removal of tissue or antibiotics, so calling early is better than waiting for the bleeding to become heavy.
Women with von Willebrand disease, an inherited clotting disorder, have a higher risk of heavy bleeding after birth.26PubMed Central. Von Willebrand disease (VWD) and pregnancy: a comprehensive overview Even with preventive clotting treatment, about 18 in 100 women with it still had severe bleeding.27PubMed. Higher-dosed clotting factor prophylaxis fails to reduce postpartum hemorrhage in women with von Willebrand disease: findings from the observational PRegnancy and Inherited bleeding DisordErS study Clues include long heavy periods, frequent nosebleeds, easy bruising, or relatives with similar bleeding. If you have it or these signs, make sure your birth team knows. Before going home, ask whether you lost a lot of blood at delivery or had any placenta concerns, and whether you are anemic and should take iron.
What Happens If You Go In for Bleeding
Staff usually first make sure you are stable by checking pulse and blood pressure and judging how much you are bleeding. If you are unwell, they may start treatment before any tests are finished. Blood may be drawn to check for anemia and sometimes your clotting. Blood tests and exams alone often can’t show the cause, so an ultrasound is usually the main scan used.28PubMed Central. Pelvic ultrasonography of the postpartum uterus in patients presenting to the emergency room with vaginal bleeding and pelvic pain The ultrasound is painless, uses a probe on the belly, and can show whether tissue or blood clots remain inside the womb.
It helps to bring or say how many days it has been since the birth and what type of delivery you had, how many pads you soaked in what time, and how large the clots were. Mention any fever, smell or dizziness, and whether you are breastfeeding, since that affects medicine choices.
Treatment depends on the cause: medicines to make the womb contract, removing leftover placenta, or repairing tears.29PubMed. Management of post-partum haemorrhage A balloon placed in the womb, fluids or blood transfusion, and rarely blocking bleeding arteries can also be used.30PubMed. Management of post-partum haemorrhage If the ultrasound shows retained tissue, a doctor may remove it with a minor procedure, often under anesthesia. The balloon presses against the bleeding surface from inside and is usually removed after a day or so once bleeding has stopped. Transfusions and arterial procedures are reserved for severe bleeding, and most women who go in for bleeding do not need them.
