Symptoms That Always Need Immediate Attention
Some symptoms during pregnancy should never be waited out. If you experience any of the following, contact your maternity unit or emergency services without delay:
- Heavy vaginal bleeding at any stage of pregnancy
- Severe abdominal pain that does not ease
- Signs of pre-eclampsia: severe headache, visual disturbances, sudden swelling, right-sided upper abdominal pain
- Reduced or absent fetal movement after 24 weeks
- Fever above 38°C (especially with aches, difficulty breathing, or rash)
- Difficulty breathing or chest pain
- Fainting or loss of consciousness
- Any trauma to the abdomen (accident, fall)
The rule is simple: if you are concerned, call. Your midwife and maternity unit would always rather hear from you than not. There is no such thing as calling too early.
Symptoms to Report Within 24 Hours
These symptoms are not emergencies but should be reported to your care provider the same day or within 24 hours. Do not leave them until your next scheduled appointment:
- Any vaginal bleeding (even light spotting after the first trimester)
- A urinary tract infection (burning, pain, or cloudy urine)
- Persistent vomiting preventing you from keeping fluids down
- Significant reduction in your baby's normal movement pattern
- Itching, particularly on the palms and soles (possible obstetric cholestasis)
- Persistent headache not responding to paracetamol
- Swelling that is sudden or asymmetric (one leg much more swollen than the other)
Normal Discomforts vs Warning Signs
Many pregnancy symptoms that feel alarming are entirely normal. The distinction between normal discomfort and warning sign comes down to severity, suddenness, and pattern.
| Usually normal | Needs assessment |
|---|---|
| Mild cramping / round ligament pain | Severe or one-sided abdominal pain |
| Light spotting in first weeks | Any bleeding after 12 weeks |
| Nausea and vomiting (first trimester) | Vomiting preventing fluid intake |
| Braxton Hicks contractions | Regular, strengthening contractions before 37 weeks |
| Mild ankle swelling at end of day | Sudden severe facial or hand swelling |
Frequently Asked Questions
What bleeding during pregnancy is normal vs concerning?
Light spotting in early pregnancy (implantation bleeding) can be normal. However, any heavy bleeding, bleeding with pain or cramping, or bleeding after 12 weeks should be assessed promptly. Bleeding in the second or third trimester always warrants same-day medical review. When in doubt, contact your care provider — no one will judge you for calling.
When should I go to hospital immediately during pregnancy?
Go immediately for: heavy vaginal bleeding, severe abdominal pain, signs of pre-eclampsia (sudden severe headache, vision changes, significant facial/hand swelling, pain under the ribs), reduced or absent fetal movement after 24 weeks, fever above 38°C, difficulty breathing, or if you have had a fall or accident. Do not wait for a scheduled appointment.
What is pre-eclampsia and how do I spot it?
Pre-eclampsia is a pregnancy complication involving high blood pressure and organ stress, typically developing after 20 weeks. Warning signs include: severe headache that won't respond to paracetamol, visual disturbances (blurred vision, flashing lights), sudden swelling of face, hands or feet, pain under the ribs on the right side, and nausea or vomiting in the second/third trimester. Pre-eclampsia can develop quickly and is a medical emergency. Call your midwife or maternity unit immediately if you have these symptoms.
How do I know if reduced fetal movement is serious?
You should be able to feel your baby move regularly from around 24 weeks. There is no 'normal' number of movements — what matters is your baby's individual pattern. If you notice a significant change in your baby's usual pattern, do not wait. Contact your maternity unit immediately. Kick-counting apps and the advice to 'drink something cold and lie down' should not replace immediate medical contact if movement has changed.
