19 Pregnancy Warning Signs: When to Call a Doctor Immediately

Quick answer

Go to hospital immediately for heavy bleeding, severe one-sided abdominal pain, reduced baby movements, waters breaking, contractions before 37 weeks, a severe headache with visual changes, sudden swelling of the face or hands, or a fit. Call your doctor the same day for fever, intense itching of the palms and soles, burning urination, or persistent vomiting. When in doubt, be seen.

Key takeaways

• Reduced baby movements is the most time-critical symptom in this article. Do not wait until morning, and do not try cold drinks, sugar or lying down to "wake" the baby first. Go and be checked.

• You never need anyone's permission to go to hospital. If a family member says wait until morning, go anyway. Doctors would far rather see you unnecessarily than late.

• Severe headache with visual changes and upper abdominal pain is a combination to memorise. It can indicate pre-eclampsia, which develops quickly and is treatable when caught.

• Intense itching without a rash, especially on palms and soles, is not a skin problem. It needs a blood test the same day.

• Save 102 and 108 in your phone now, along with your hospital's number and your doctor's. Do not be searching for them in an emergency.

How to use this page

Pregnancy symptoms are not all equally urgent, and a flat list of warning signs makes it harder to tell the difference. This page is sorted by how fast you need to act.

If you are unsure which tier a symptom belongs to, treat it as the more urgent one. No obstetrician will be annoyed with you for coming in.

Go to hospital now: 12 signs

1. Heavy vaginal bleeding

Any bleeding in pregnancy should be reported. Go immediately if you are soaking through a pad in an hour or less, passing clots, or bleeding with pain.

Do not take anything to try to stop it. Bleeding in pregnancy is assessed, not treated at home.

2. Severe one-sided abdominal pain, shoulder tip pain or faintness in early pregnancy

This combination can indicate an ectopic pregnancy, where the pregnancy has implanted outside the uterus. It is a medical emergency and can develop rapidly.

Shoulder tip pain with abdominal pain is the specific pattern to know. It is caused by internal bleeding irritating the diaphragm, and it is easy to dismiss as a muscle ache.

3. Reduced or changed baby movements

This is the single most important symptom in later pregnancy, and the one most often delayed.

• Go and be checked the same day, at any hour. Do not wait until morning

• Do not try to make the baby move first. Cold drinks, sweet food, lying down, poking the bump and ice packs are all commonly advised and all waste time. If the pattern has changed, go

• There is no set number of movements to count. What matters is a change from what is normal for your baby

• Never assume "the baby is just sleeping" or "there is less room now." Reduced movement in late pregnancy is not caused by lack of space

This applies however many times you have already been. Repeated visits for reduced movements are appropriate and expected, not an inconvenience.

4. Waters breaking, or any leaking of fluid

Whether a gush or a slow trickle. Note the time, the colour and the smell, and go in.

Green or brown fluid needs immediate attention, as does any fluid leak before 37 weeks.

5. Regular contractions or tightening before 37 weeks

Pain or tightening that comes and goes in a rhythm, especially if the intervals are shortening. It may feel like period pain, backache in waves, or pelvic pressure rather than classic contractions.

Back-dominant preterm labour is frequently mistaken for a bad back. If back pain is coming in waves before 37 weeks, call your hospital.

6. Severe headache, especially with visual changes

A severe or persistent headache that does not settle with rest and paracetamol, particularly with flashing lights, blurred or double vision, or spots in your vision.

7. Pain under the ribs, or in the upper right abdomen

Often described as severe indigestion that will not shift. This is a classic and frequently missed sign of pre-eclampsia and related complications.

8. Sudden swelling of the face, around the eyes, or of the hands

Swelling of the feet and ankles by evening is normal in pregnancy. Sudden swelling of the face or hands is not, particularly alongside headache, visual changes or rapid weight gain over a few days.

The pre-eclampsia combination worth memorising: severe headache, visual changes, pain under the ribs, and sudden swelling of the face or hands. Any one of these needs attention. Together they need it urgently.

9. A fit or seizure

Call an ambulance. This is an emergency at any stage of pregnancy.

10. Chest pain, breathlessness at rest, or coughing up blood

Needs immediate assessment. Breathlessness on climbing stairs in late pregnancy is common. Breathlessness at rest, or with chest pain, is not.

11. Pain, swelling, warmth or redness in one calf

Usually one leg only. Pregnancy increases clotting risk, and a clot in the leg can travel.

Do not massage the area or apply heat while waiting to be seen.

12. Any fall, road accident, or blow to the abdomen

Go and be checked even if you feel completely fine, and even if the impact seemed minor. Problems after abdominal trauma in pregnancy can develop over hours without obvious symptoms.

This includes any physical assault. If you are being hurt at home, that is a medical emergency as well as a safety one, and hospital staff can help you access support. In India, the women's helpline 181 is available nationally.

13. Fever or chills

A temperature above 38°C, or a fever with shivering, needs assessment the same day, particularly with abdominal tenderness, foul-smelling discharge or pain when passing urine.

Take paracetamol while arranging to be seen. Treating fever in pregnancy matters, especially in the first trimester.

14. Intense itching, especially on the palms and soles

Itching without any visible rash, worse at night, on the palms and soles, particularly in the second half of pregnancy, can indicate intrahepatic cholestasis of pregnancy. This is a liver condition associated with increased risk for the baby, and it is managed by monitoring and by planning delivery timing.

It is diagnosed with a blood test, not by looking at your skin. Do not buy a cream and wait.

15. Burning urination, or pain in your side

Urinary infections are common in pregnancy and can progress to kidney infection, which is a genuine risk. Do not wait it out or treat it with home remedies.

16. Persistent vomiting, or inability to keep fluids down

If you have not kept fluids down for 24 hours, or you are passing very little or dark urine, you need assessment. This may be hyperemesis gravidarum, which is treatable and should not be endured.

17. Foul-smelling, green, grey or frothy vaginal discharge, or vaginal itching

Increased discharge in pregnancy is normal if it is thin, clear or milky and not itchy. A change in colour or smell needs treating.

18. Dizziness or fainting episodes

Occasional light-headedness on standing quickly is common. Repeated dizziness, or actually fainting, needs checking, since anaemia and low blood pressure are both common and treatable.

19. A persistent headache that is not settling

Even without visual changes, a headache that lasts more than a few hours and does not respond to rest, fluids and paracetamol should be reported, particularly after 20 weeks.

Mention at your next visit

These are worth raising but do not need an urgent call.

• Constipation, piles or heartburn

• Mild swelling of feet and ankles by evening

• Mild cramping or a pulling sensation low down

• Tiredness, disturbed sleep, or trouble getting comfortable

• Appetite changes and food aversions

• Bleeding gums

• Leg cramps at night

• Mood changes, or feeling low. Raise this properly rather than mentioning it in passing, since mental health in pregnancy is treated, not endured

• Restless legs, or craving non-food items such as mud or chalk, which often indicate iron deficiency

Our guide to common and awkward pregnancy symptoms covers what is normal in more detail.

What changes by trimester

The same symptom can mean different things at different stages.

Practical preparation

Do this once, now, rather than in an emergency.

• Save in your phone: your doctor's number, your hospital's labour ward number, the ambulance numbers 102 and 108, and one person who can take you

• Keep your antenatal card or file where someone else can find it. Take it every time

• Know the route to your hospital at night, and have a backup plan if your usual transport is not available

• Tell one family member the "go now" list, so someone else in the house recognises the signs

• Do not drive yourself if you have bleeding, severe pain, visual changes or dizziness

• Know whether your pregnancy has been marked high risk, and where you have been told to go if so

In India, free ambulance services are available on 102 and 108 in most states, and free antenatal care and delivery services are available at government facilities. Cost should never be the reason you delay being seen.

A note about being told to wait

This part is not medical, but it matters.

In many Indian households, the decision to go to hospital at night is not the pregnant woman's alone. It gets weighed against disturbing people, the cost of transport, "it is probably nothing," and the assumption that it can wait until the morning clinic.

It usually can wait. But the symptoms on the "go now" list are exactly the ones where it cannot. Reduced baby movements, heavy bleeding and the pre-eclampsia combination are all time-sensitive, and outcomes are meaningfully better when they are seen early.

You do not need agreement to go. If you are worried, that is sufficient reason. Doctors and hospital staff will not think you overreacted, and a normal check is a good outcome, not a wasted trip.

Frequently asked questions

How do I know if the baby's movements have reduced?
By comparing with your baby's own usual pattern rather than a fixed number. Any change, whether fewer, weaker or a different pattern, should be checked the same day.

Should I drink cold water or juice to make the baby move?
No. These methods are widely recommended and simply delay assessment. If the pattern has changed, go and be checked.

Is it normal to have some bleeding in pregnancy?
Light spotting happens in some pregnancies and is often harmless, but it should always be reported so it can be assessed. Heavy bleeding or bleeding with pain means going in immediately.

What are the warning signs of pre-eclampsia?
Severe headache, blurred vision or flashing lights, pain under the ribs or upper right abdomen, sudden swelling of the face or hands, and rapid weight gain. Any of these after 20 weeks needs urgent assessment.

My palms and soles itch badly at night. Is that serious?
It can be. Intense itching without a rash, especially on palms and soles, may indicate a liver condition of pregnancy that needs a blood test and monitoring. Contact your doctor the same day.

I had a small fall but feel fine. Do I need to go?
Yes. Get checked even if you feel completely well, since problems after abdominal trauma can develop over hours.

What is the difference between Braxton Hicks and real contractions?
Braxton Hicks are irregular, usually painless, and settle with rest or a position change. Contractions come in a rhythm, become stronger and closer together, and do not settle. Before 37 weeks, rhythmic tightening should be assessed.

Is it okay to call my doctor at night?
Yes. Maternity units are staffed 24 hours, and this is exactly what they are there for.

I have gone in twice already and everything was fine. Should I go again?
Yes. Each episode is assessed separately, and repeated visits for reduced movements or bleeding are appropriate. Never let a previous normal result stop you going.

The bottom line

Not every pregnancy symptom is urgent, but a specific handful genuinely are, and knowing them by heart is worth more than any other preparation you make. Heavy bleeding, severe one-sided pain in early pregnancy, reduced baby movements, waters breaking, contractions before 37 weeks, and the pre-eclampsia combination of headache, visual changes, rib pain and sudden swelling all mean going in now rather than waiting for morning. Save the numbers today, tell someone else at home the list, and go whenever you are worried.
