You've given birth, the baby is here — and suddenly you feel strong cramps in your abdomen. Not labor contractions this time, but afterpains. Uterine contractions after birth that can surprise even the most prepared new mother.
Here you'll find out what afterpains are, why they occur, and what you can do to relieve the pain.
What Are Afterpains?
Afterpains are contractions of the uterus after birth. Your uterus weighs about 2 lbs / 1 kg right after delivery. Over the next 6–8 weeks, it will shrink back to its normal size of just 2 oz / 50–60 grams.
This process is called involution, and afterpains are the body's way of doing it. The uterine muscle contracts to push out remaining tissue and reduce bleeding.
Afterpains feel like painful cramps in the abdomen — many compare them to strong period cramps or mild labor contractions. They come in waves, and they are a sign that your body is doing exactly what it should.
Afterpains are not dangerous. On the contrary, they are a good sign that the uterus is healing as it should. The pain is temporary and usually subsides after 2–4 days.
Why Do Afterpains Occur After Birth?
The hormone oxytocin plays a key role. Oxytocin causes the uterine muscle to contract, helping the uterus return to its normal size and closing the blood vessels where the placenta was attached.
Oxytocin is released in large amounts:
- During breastfeeding — when the baby suckles at the breast, oxytocin production is stimulated. This is the most common trigger for afterpains.
- After the placenta is delivered — the body immediately begins producing oxytocin to shrink the uterus.
- With skin-to-skin contact — closeness with the baby can also trigger oxytocin.
The connection between breastfeeding and afterpains is clear. Many people feel the cramps start the moment the baby is latched on. Finding comfortable breastfeeding positions can make nursing more manageable when afterpains are painful.
Who Gets the Worst Afterpains?
Not everyone experiences afterpains equally. Here are the most important factors:
First-Time Parents
Surprisingly, afterpains are actually uncommon among first-time parents. The uterus has good muscle tone and contracts evenly without strong cramping.
Second (and Later) Births
Afterpains are usually stronger after the second, third, and subsequent births. This is because the uterine muscle has been stretched multiple times and needs stronger contractions to recover.
The more births you've had, the more intense the afterpains can be. This is completely normal.
Other Factors
- Large baby or excess amniotic fluid — the uterus has been more stretched
- Twin pregnancy — double the expansion requires stronger contractions
- Breastfeeding — active breastfeeding intensifies afterpains
Contact your midwife or doctor if you experience severe pain that is not relieved by standard over-the-counter pain relief, fever over 100.4°F / 38°C, or bleeding that suddenly increases significantly. These symptoms may indicate an infection or complication.
How Long Do Afterpains Last?
Most people find that afterpains are strongest in the first 1–2 days after birth. They then gradually subside.
Typical timeline:
- Day 1–2: Strongest, especially during breastfeeding
- Day 3–4: Noticeable improvement, clearly decreasing
- Day 5–7: Most people barely feel them anymore
- After 1 week: Usually completely gone
In people who have had previous births, afterpains may last slightly longer and feel stronger in the first days. But they too subside within the first week.
What Relieves Afterpains?
There are several things you can do to manage the pain:
Pain Relief
Over-the-counter pain relievers such as acetaminophen (Tylenol) and ibuprofen (Advil/Motrin) can be taken while breastfeeding. Talk to your midwife or doctor about the correct dosage.
It's a good idea to take pain relief 30–45 minutes before breastfeeding, so the effect is at its peak when the afterpains kick in.
Heat
Heat can relieve the cramps effectively:
- Heating pad or hot water bottle on the abdomen
- Warm blanket over the lower abdomen
- Warm bath (when your midwife or doctor gives the all-clear)
Lie on Your Stomach
Lying on your stomach can help the uterus contract back more quickly. Many people find this also relieves the pain. Place a pillow under your abdomen for extra comfort.
Breathing Exercises
Deep, slow breaths through the cramps can make them easier to manage. The technique is similar to what you may have used during labor.
Acupuncture
Some maternity wards offer acupuncture for afterpains. Ask your midwife whether this is available where you are.
Try to empty your bladder regularly. A full bladder presses against the uterus and can worsen afterpains. Go to the bathroom at least every two hours in the first few days.
Afterpains and Breastfeeding
The connection between afterpains and breastfeeding is something many new mothers find challenging. The baby latches on, oxytocin is released, and the cramps begin.
It can feel like a vicious cycle, but it's actually a good thing. Breastfeeding helps the uterus return to its normal size faster, and it reduces postpartum bleeding.
Tips for managing afterpains during breastfeeding:
- Take pain relief 30–45 minutes before nursing
- Use heat on your abdomen while nursing
- Focus on your breathing through the cramps
- Remember that it only lasts a few days
Afterpains and Physical Activity
The first days after birth are about rest. But light movement such as short walks can actually help the body in the healing process.
Be aware that physical activity can temporarily increase bleeding. If you notice this, it's a signal to take it easier.
Once the afterpains have subsided after the first week, you can gradually begin gentle pelvic floor exercises.
When Should You Contact a Healthcare Provider?
Afterpains are normal and harmless. But there are situations where you should reach out:
- Pain that does not subside after 7 days
- Pain that is not relieved by over-the-counter pain relief
- Fever in combination with abdominal pain
- Foul-smelling discharge together with cramps
- Heavy bleeding that does not decrease
These symptoms may indicate an infection in the uterus and require medical evaluation.
Summary
Afterpains are the body's natural way of recovering after birth. They are uncomfortable but short-lived and harmless. For most people they last 2–4 days and can be relieved with heat, pain relief, and breathing exercises.
Remember that you have just done something completely extraordinary. Your body needs time to recover. Learn more about physical healing after birth and the postpartum period for a complete overview of what to expect.
Frequently Asked Questions
How long do afterpains last after birth?
Most people find that afterpains are strongest in the first 1–2 days after birth and noticeably decrease after 3–4 days. After a week they are usually completely gone. In those who have had previous births, afterpains may last slightly longer and feel stronger, but they also subside within the first week.
Why are afterpains worse with the second birth?
Afterpains are usually stronger after the second, third, and subsequent births. This is because the uterine muscle has been stretched multiple times and needs stronger contractions to return to its normal size. The more births you've had, the more intense the afterpains can be.
Can I take pain relief for afterpains while breastfeeding?
Yes, both acetaminophen (Tylenol) and ibuprofen (Advil/Motrin) can be used while breastfeeding to relieve afterpains. A good tip is to take pain relief 30–45 minutes before nursing, so the effect is at its peak when oxytocin is released and afterpains kick in. Ask your doctor or midwife about correct dosage.
Are afterpains a sign that something is wrong?
No, afterpains are a good sign. They mean the uterus is contracting as it should after birth. However, do contact a healthcare provider if the pain does not subside after 7 days, is not relieved by pain relief, or occurs together with a fever over 100.4°F / 38°C or foul-smelling discharge. Those may be signs of infection.
Does lying on your stomach help with afterpains?
Yes, many people find it helps to lie on their stomach. The position can help the uterus contract back more quickly, and many find it relieves the pain. Place a pillow under your abdomen for extra comfort. Heat on the abdomen — for example a heating pad — can also provide good relief.
