Quick facts
- Most common trimester
- 2nd and 3rd
- Typical trigger
- Coughing, sneezing, laughing, exercise
- What helps most
- Regular pelvic floor exercises
- Key thing to rule out
- Waters breaking, not just a leak
- See a doctor if
- Leaking is heavy, constant, or you're unsure it's urine
A little leak when you laugh too hard, sneeze suddenly, or push through the last few reps of a workout is a very common (if not always talked about) part of later pregnancy. It happens to a large number of pregnant people and usually isn't a sign of anything wrong.
Still, it's worth understanding why it happens, what genuinely helps, and — importantly — how to tell an occasional leak apart from your waters breaking, since the two can sometimes feel similar.
What is urinary incontinence in pregnancy?
Urinary incontinence in pregnancy usually means stress incontinence: small, involuntary leaks of urine triggered by pressure on the bladder, such as coughing, sneezing, laughing, jumping or lifting. It's different from frequent urination, which is simply needing to go to the toilet more often.
It becomes more common from the second trimester onwards as your growing womb adds weight and pressure on your bladder and pelvic floor — the sling of muscles that support your bladder, womb and bowel. It's extremely common, affecting a large proportion of pregnant people to some degree, and for most it improves after birth, especially with pelvic floor exercises.
You're not alone — and it's not permanent
Pregnancy-related stress incontinence is one of the most under-discussed but common symptoms of later pregnancy. For most people it improves significantly in the months after birth, particularly with regular pelvic floor exercise.
What causes urinary incontinence in pregnancy?
A combination of hormonal softening and mechanical pressure explains most pregnancy-related leaking.
Pressure from your growing baby and womb
As your baby and womb grow, they add direct weight and pressure onto your bladder, especially once the head engages in the pelvis in the third trimester.
Hormonal softening of pelvic floor tissue
The hormone relaxin, along with progesterone, softens ligaments and muscles throughout the pelvis, including the pelvic floor that supports your bladder — this makes it a little less effective at holding everything firmly in place.
A weakened pelvic floor
If your pelvic floor was already under-exercised before pregnancy, or you've had children before, you may be more prone to leaks as pregnancy adds extra load.
Coughing, sneezing, laughing or straining
Any sudden increase in pressure inside your abdomen — even a hearty laugh — briefly overwhelms your pelvic floor's ability to hold everything closed.
It's more likely if…
- This isn't your first pregnancy
- You're carrying twins or more
- You have a persistent cough or constipation, which strain the pelvic floor
- You're further along in the third trimester
When leaking is normal
Occasional small leaks are a common, manageable part of later pregnancy. It's reassuring when:
- Leaks are small and clearly linked to a cough, sneeze, laugh or exercise.
- You can predict and largely control it, e.g. by emptying your bladder before activity.
- There's no pain, burning or unusual smell when you urinate.
- You feel otherwise well, with no fever or tummy pain.
| Usually normal (stress incontinence) | Needs checking | |
|---|---|---|
| Trigger | Coughing, sneezing, laughing, exercise | No clear trigger; happens continuously |
| Amount | A small dribble | A gush, or ongoing trickle you can't stop |
| Control | You can usually predict and limit it | You have no control over it at all |
| Other signs | None | Pain, burning, fever, or before 37 weeks with a constant trickle |
A simple check: does it stop?
Urine leaks with stress incontinence typically stop once the trigger (the cough, sneeze or laugh) passes. Fluid that keeps trickling regardless of what you're doing is more likely to be amniotic fluid and needs checking.
Warning signs — get checked
Contact your midwife or maternity unit promptly if you notice any of the following, as they can point to a urinary tract infection or, importantly, your waters breaking rather than a simple leak:
Seek urgent medical care if you have
- A sudden gush of fluid, or a continuous trickle you can't control — possible waters breaking.
- Fluid loss that isn't linked to coughing, sneezing or straining.
- Pain or burning when you pass urine.
- Cloudy, strong-smelling, or blood-stained urine.
- Fever, chills, or lower tummy/back pain alongside leaking.
- Any fluid loss before 37 weeks that you're not sure is urine.
If you think your waters may have broken, contact your maternity unit straight away rather than waiting — this is especially important before 37 weeks. As always, contact your maternity unit the same day if your baby's movements feel reduced.
When it's hard to tell urine from waters
If you genuinely can't tell whether you're leaking urine or amniotic fluid, treat it as possible waters breaking and get checked — a simple test at your maternity unit can confirm which it is.
Self-care and pelvic floor exercises
Pelvic floor exercises are the single most effective thing you can do, alongside some practical everyday adjustments.
Pelvic floor exercises (Kegels)
- Squeeze and lift the muscles you'd use to stop yourself passing wind and stop the flow of urine, hold for a few seconds, then release.
- Aim to do these regularly through the day — tying them to routine moments (brushing teeth, waiting for the kettle) helps you remember.
- Ask your midwife or a women's health physiotherapist to check your technique if you're not sure you're doing them correctly.
Everyday adjustments
- Empty your bladder before exercise, long journeys or anything that involves coughing or straining.
- Cross your legs or brace your pelvic floor just before you cough or sneeze if you can.
- Wear a thin panty liner for reassurance during exercise or busy days.
Manage triggers
- Treat any persistent cough promptly, as repeated coughing strains the pelvic floor.
- Avoid constipation and straining on the toilet — eat enough fibre and stay hydrated.
- Maintain a healthy pregnancy weight gain as advised by your midwife, as extra weight adds pressure too.
It usually gets better
For most people, stress incontinence eases in the months after birth, especially with consistent pelvic floor exercise. If it persists well after your baby arrives, ask your GP about a referral to a women's health physiotherapist.
When to consult a doctor or midwife
Speak to your midwife or doctor if:
- Leaking is frequent, heavy, or significantly affecting your daily life.
- You're not confident telling the difference between urine leaks and amniotic fluid.
- You have any pain, burning or other signs of a urinary infection alongside leaking.
- Pelvic floor exercises haven't helped after several weeks of regular practice.
- You'd like guidance from a women's health physiotherapist.
Keep notes for your midwife
Tracking how often leaks happen and what triggers them helps your midwife advise you and rule out anything else going on.
Open the Pregnancy TrackerFrequently asked questions
Is leaking urine in pregnancy normal?
Yes, small leaks when coughing, sneezing, laughing or exercising are very common from the second trimester onwards, caused by pregnancy hormones softening the pelvic floor and your growing baby adding pressure on the bladder. It's not usually a sign of a problem, and pelvic floor exercises help.
How do I tell if I'm leaking urine or my waters have broken?
Urine leaks are usually small, linked to a clear trigger like coughing or laughing, and stop once the trigger passes. Waters breaking typically feels like a sudden gush or a continuous trickle you can't control, regardless of what you're doing. If you're unsure, contact your maternity unit — they can test to confirm.
Do pelvic floor exercises actually help with pregnancy incontinence?
Yes, regular pelvic floor exercises are the most effective self-help measure for pregnancy-related stress incontinence, and they also support recovery after birth. Ask your midwife to check your technique if you're not sure you're doing them correctly.
Will incontinence go away after I give birth?
For most people, symptoms improve significantly in the weeks and months after birth, especially with continued pelvic floor exercise. If leaking persists or doesn't improve, ask your GP about seeing a women's health physiotherapist.
Can a UTI cause leaking as well as frequent urination?
Yes, a urinary tract infection can sometimes make urgency and leaking worse, alongside pain or burning when you wee and cloudy or strong-smelling urine. If you notice these together, see your doctor promptly, as UTIs need treatment in pregnancy.
Is it safe to keep exercising if I leak urine during workouts?
Generally yes — light leaking during exercise is common and not usually a reason to stop activity that your doctor or midwife has approved. Emptying your bladder beforehand, wearing a liner, and building your pelvic floor strength can all help you exercise comfortably.
