Leaking urine in pregnancy: why it happens and how to tell it from waters breaking

Losing a few drops of urine when you sneeze, laugh or climb stairs can be annoying, but you are not alone. It is very common in pregnancy, and for most people it improves or clearly lessens after birth.

Why does it happen?

The growing womb presses on the bladder. Pregnancy hormones also loosen the tissues that support the bladder and urinary tract. In moments when pressure inside the abdomen rises, such as coughing, sneezing, laughing, bending or jumping, the bladder outlet may not keep up. This is called stress urinary incontinence. It is more common later in pregnancy and in repeat pregnancies.

Urine or waters breaking?

Sometimes it is hard to be sure whether the fluid is urine or the amniotic fluid surrounding your baby. These clues may help:

• Urine is usually yellow with a clear smell; amniotic fluid is usually clear, pale and odourless, or slightly sweet-smelling.
• Urine leaks are brief and linked to moments like coughing; fluid from the waters may keep coming or return repeatedly.
• You can stop urine by squeezing your muscles; amniotic fluid usually cannot be stopped.
• If you are unsure, lie down with a clean pad; if the pad keeps getting wet, do not wait, call.

Do not try to decide on your own. If you suspect your waters have broken, note the time and contact your doctor or your birth hospital. For discharge and bleeding, see the Guide article “Vaginal discharge and bleeding in pregnancy”.

8 tips that help right away

1. Do your Kegel exercises regularly; the Kegel programme in the app can keep you company. For details see the Guide article “Kegel and pelvic floor exercises”.
2. Try briefly tightening your pelvic floor just before you sneeze or cough.
3. Empty your bladder every 2–3 hours; do not hold on for too long.
4. Lean slightly forward on the toilet to empty the bladder fully.
5. Do not cut down on water during the day; concentrated urine can irritate the bladder more. You can adjust the amount in the evening.
6. Reducing caffeinated drinks eases bladder irritation in some people.
7. Eat plenty of fibre to avoid constipation; straining loads the pelvic floor.
8. A thin pad or spare underwear in your bag can boost your confidence.

After birth

For most people, leaking lessens in the weeks and months after birth. Regular pelvic floor exercises support this. If it is still there after a few months, it helps to see a doctor or a pelvic floor physiotherapist.

Do not blame yourself

Leaking urine may feel embarrassing, but it is not a flaw; it is a sign that your body is doing a demanding job. Telling your doctor or midwife openly is the first step to finding the right support, and they hear this question often. If privacy worries you, saying “I would like to ask something” at the start of the visit is enough.

When to contact your doctor

• Fluid keeps coming or returns repeatedly, the pad gets wet and you suspect your waters have broken (tell someone without waiting)
• The fluid is green, bloody or foul-smelling
• You have burning when passing urine, frequent urgent trips, back pain, fever or cloudy urine
• You cannot pass urine at all or struggle to empty your bladder
• Leaking seriously limits daily life
• If you suspect your waters have broken and also have reduced baby movements, abdominal pain or bleeding, or feel faint, call 112 (in Turkey) or your local emergency number
