Stomach (abdominal) pains or cramps are common in pregnancy. They're usually nothing to worry about, but they can sometimes be a sign of something more serious that needs to be checked. It's probably nothing to worry about if the pain is mild and goes away when you change position, have a rest, do a poo or pass wind. But if you have stomach pains and are worried, call your midwife or maternity hospital. Harmless stomach pains, which can be dull or sharp, may be caused by:
Urgent advice: Call your midwife immediately if you have stomach pain and:
- bleeding or spotting
- regular cramping or tightenings
- vaginal discharge that's unusual for you
- lower back pain
- pain or burning when you pee
- the pain is severe or does not go away after you've rested for 30 to 60 minutes
Any of these could be the symptoms of something that needs to be checked or treated urgently.
Possible causes of serious stomach pain
Some conditions that can cause stomach pain need to be checked urgently.
Ectopic pregnancy
This is when a fertilised egg implants outside the womb, for example in a fallopian tube. The pregnancy cannot survive and needs to be removed with medicine or surgery.
Symptoms typically appear between 4 and 12 weeks of pregnancy and can include:
- tummy pain and bleeding
- pain in the tip of your shoulder
- discomfort when pooing or peeing

Miscarriage
Cramping pains and bleeding before 24 weeks of pregnancy can sometimes be a sign of miscarriage or threatened miscarriage (when you bleed but the pregnancy normally continues).
Pre-eclampsia
Pain just under the ribs is common in later pregnancy due to the growing baby and uterus pushing up under the ribs.
But if this pain is bad or persistent, particularly on the right side, it can be a sign of pre-eclampsia (high blood pressure in pregnancy) which affects some pregnant women. It usually starts after 20 weeks or just after the baby is born.
Other symptoms of pre-eclampsia include:
- severe headache
- vision problems
- swollen feet, hands and face
You'll need to be monitored in hospital.

Premature labour
If you're less than 37 weeks pregnant and are having regular abdominal cramps or tightenings, call your midwife.
This could be a sign of premature labour, and you'll need to be monitored in hospital.
Placental abruption
This is when the placenta starts to come away from the wall of the womb, usually causing bleeding and constant severe pain that does not come and go like a contraction pain.
It's sometimes an emergency because it means the placenta may not be able to support your baby properly.
You should go to the hospital so you and your baby can be checked.

UTI (urinary tract infection)
UTIs are common in pregnancy and can usually be easily treated. They can cause tummy pain and sometimes, but not always, pain when you pee.
Find out more about UTIs
Abdominal or tummy pain is common during pregnancy. In the first trimester (weeks 0 to 12) it is common to feel mild pains in the lower tummy area. These are caused by hormonal changes and by your growing womb. Urgent advice: Contact your midwife or GP urgently if:
- the tummy pain is severe
- the tummy pain feels like tightening. Tightening of your tummy could be a sign that you are having a contraction and may be going into labour. During a contraction your womb often goes hard to touch, and your abdomen can feel very tight
- you have any bleeding from your vagina
- the pain is in your upper tummy area, especially if it is on the right hand side, as this could be a sign of pre-eclampsia
- you have symptoms like pain on passing urine (peeing), high temperature, needing to pee more than normal and cloudy or smelly wee. These are all signs of a urinary tract infection.
What causes severe or sharp tummy pain in pregnancy?
In the first trimester (weeks 0 to 12) sharp or severe tummy pain could be due to:
- an ectopic pregnancy
- a miscarriage
- a urinary tract infection
- constipation or trapped wind
In the second and third trimester, severe tummy pain could be due to:
- urinary tract infections or constipation
- placental abruption
- premature or preterm labour if you are less than 37 weeks pregnant
- pre-eclampsia if you are more than 20 weeks pregnant. Other symptoms are a headache, swelling of hands, feet and/or face, blurred vision or seeing flashing lights or spots in front eyes and nausea or vomiting.
