Pregnancy symptom check
When to call, when to wait, when it’s an emergency
Tick what you’re experiencing
🚨 Always call your maternity unit straight away for:
- Reduced or absent fetal movements (after 24 wk) — this is THE single most important pregnancy red flag.
- Vaginal bleeding heavier than light spotting.
- Severe headache + visual changes (flashing lights, blurring) + swelling of face/hands — possible pre-eclampsia.
- Severe abdominal pain not relieved by rest.
- Sudden swelling, redness, or pain in one calf — possible DVT.
- Sudden breathlessness or chest pain — possible pulmonary embolism.
- Trickle / gush of clear fluid from vagina before 37 weeks — possible PPROM.
- Persistent itching of palms / soles, worse at night — possible cholestasis (ICP).
Self-care tips for common pregnancy discomforts
- Morning sickness — small frequent meals, ginger, vitamin B6 (10–25 mg), avoiding triggers. Paracetamol if needed. Severe vomiting → see hyperemesis pathway.
- Heartburn / reflux — smaller meals, prop up the head of the bed, avoid late-evening eating, antacids (Gaviscon) and PPIs (omeprazole) safe in pregnancy.
- Backache — pregnancy pillow between knees while sleeping on left side, supportive shoes, prenatal yoga / physio, paracetamol if needed. Avoid NSAIDs after 30 wk.
- Constipation — water + fibre + movement; pregnancy-safe laxatives (lactulose, Movicol).
- Fatigue — common 1st & 3rd trimester. Iron deficiency is a frequent contributor — check ferritin at booking.
- Round ligament pain — brief sharp pain with movement, 2nd trimester. Slow position changes, gentle exercise.
- Braxton-Hicks contractions — tightening without pattern or cervical change. Hydrate, rest. Painful or > 4/hour before 37 wk → call.
- Mild swelling (oedema) — feet/ankles, especially evenings. Elevate, compression stockings. Sudden swelling of face/hands or both legs differently → call.
- Pelvic girdle pain — physiotherapy referral, supportive belt, avoid one-leg-stand activities.
- Vaginal discharge — increased clear/white normal. Itchy, burning, foul-smelling, green/yellow — possible infection, get checked.
- Sleep disturbance — left-side sleeping after 28 wk (cuts late stillbirth risk vs supine), pillows, cool room.
- Headache — mild + settles with paracetamol = usually normal. Severe + visual disturbance + swelling = pre-eclampsia until proven otherwise.
Educational tool only — not medical advice. When in doubt, call your maternity team. Maternity units expect questions and never want you to wait when you’re worried.
What does this mean?
The hardest part of pregnancy is often knowing when something is normal pregnancy discomfort versus when to actually call. A few rules of thumb help. Reduced fetal movements after 24 weeks is the single most important red flag — never wait for movements to return. Maternity units expect these calls and would rather see you for nothing than miss something. The MBRRACE-UK reports repeatedly cite missed or delayed action on reduced movements as a stillbirth contributor. Severe headache + visual disturbance + swelling of face / hands is the pre-eclampsia triad and warrants emergency assessment regardless of how recently you were seen. Vaginal bleeding more than light spotting, severe abdominal pain, sudden breathlessness or chest pain, and swelling/pain in one calf all need same-day urgent review — these are the patterns of placental abruption, pulmonary embolism, and deep vein thrombosis. The first 12 weeks postpartum is the highest-risk window for clots; pregnancy itself raises that risk 4–5 fold over baseline. On the other side, many common discomforts — mild nausea, fatigue, heartburn, backache, Braxton-Hicks tightening, mild ankle swelling, round-ligament pain — respond to simple self-care and don’t need an appointment between routine visits. The compromise: call your midwife when in doubt. Maternity teams are explicit that they want you to call, and being “wrong” about an emergency is never the problem — missing one is.
What pregnancy symptoms are NORMAL?
Many discomforts are normal:
- Mild nausea / morning sickness (peaks 8-10 weeks).
- Breast tenderness.
- Fatigue.
- Mood swings.

Common worries explained
Bleeding in early pregnancy
~20-25% of T1 pregnancies have some bleeding; ~50% continue successfully. Always check with provider. Heavy bleeding + severe one-sided pain + dizziness = same-day A&E (ectopic risk).
Round-ligament pain
Common 14-26 weeks. Sharp pulling in groin/abdomen with movement. Brief, positional. Sustained or severe + other symptoms = call.
Breathlessness
Progesterone, diaphragm compression, anaemia. Red-flag if sudden severe + chest pain or can’t lie flat — see /calculators/pregnancy-palpitations.
Severe palm / sole itch
OBSTETRIC CHOLESTASIS (ICP). Bile acid build-up. Raises stillbirth risk if untreated. Same-day GP for bile acid + LFT bloods.
Reduced fetal movement (24+ weeks)
Call maternity unit IMMEDIATELY, regardless of time. Don’t try to wake baby first — that’s post-call assessment.
What's preeclampsia?
Pregnancy condition: blood pressure ≥ 140/90 after 20 weeks + protein in urine + sometimes other organ involvement. Affects ~3-8% of pregnancies. Red-flag symptoms: severe headache; vision changes; upper-abdominal pain (liver); sudden severe swelling; reduced urine output; sudden weight gain. Can progress rapidly. See /calculators/preeclampsia-risk.
What's hyperemesis gravidarum?
Severe nausea + vomiting + dehydration + weight loss (~5% of pre-pregnancy) + ketonuria + electrolyte disturbance. Affects ~1-3% of pregnancies. NEEDS treatment with IV fluids, IV antiemetics. See /calculators/puqe-score for the scoring tool.
What's obstetric cholestasis (ICP)?
Liver condition where bile acids back up. Affects ~1% UK / Northern European pregnancies. CLASSIC: severe ITCH especially palms and soles, often worse at night, NO RASH. Usually T3. Raises stillbirth risk if bile acids high. Bloods (total bile acids, LFTs). Treatment: ursodeoxycholic acid + induction usually offered 36-38 weeks if bile acids significantly raised.
Different scenarios — what to do
Scenario 1: 30 weeks, severe headache, vision blurry, BP at home 145/95
POSSIBLE PREECLAMPSIA. Same-day call to maternity day-case unit / triage. Bloods, urine dipstick, BP monitoring. May need admission.
Scenario 2: 14 weeks, light pink spotting, no pain
Possibly implantation-late bleed or cervical change. Call Early Pregnancy Unit or GP. Ultrasound check. Usually reassuring.
Scenario 3: 36 weeks, intense itching on palms and soles, no rash
OBSTETRIC CHOLESTASIS suspected. Same-day GP for bile acid bloods. May need ursodeoxycholic acid and earlier induction.
Scenario 4: 28 weeks, swollen ankles in evenings, no other symptoms, BP 110/70
Normal physiological swelling. Elevate feet, hydrate, compression stockings, walking. Mention at next antenatal visit.
Scenario 5: 32 weeks, baby hasn't moved as much today as usual
Call maternity unit IMMEDIATELY for assessment. Don’t wait to see if movement returns. CTG, possibly ultrasound. Most go home reassured; a small percentage are picked up early.
Care guidance — when in doubt
- If unsure, call. Maternity units would rather see you for reassurance than miss something.
- Don’t Google severe symptoms. Call.
- Know your maternity unit number by heart.
- Have your maternity notes / digital records accessible.
- Trust your gut — parental concern is a real predictor.
- Don’t worry about “being a nuisance” — you’re a patient with a developing baby.

Frequently asked questions
What symptoms are normal during pregnancy?
MANY discomforts are normal: mild nausea / morning sickness (peaks 8-10 weeks); breast tenderness; fatigue; mood swings; mild dizziness on standing quickly; backache; pelvic pressure; round-ligament pain (sharp pulling sensations in groin/abdomen, especially weeks 14-26); leg cramps; constipation; heartburn (especially T3); swollen ankles (especially T3 evenings); frequent urination; insomnia in T3; baby's hiccups (rhythmic taps); occasional Braxton Hicks (irregular tightenings, T3). All COMMON. None on their own = emergency. But certain SEVERE or COMBINED symptoms ARE red flags — see below.
What pregnancy symptoms are red flags?
URGENT same-day call / A&E: severe headache, especially with vision changes or upper-abdominal pain (preeclampsia); blurred vision / flashing lights / spots; sudden severe swelling (face, hands); sudden weight gain; severe abdominal pain (constant, not contraction-like); persistent vomiting can't keep fluids down 24h (hyperemesis); vaginal bleeding (any in T1; any heavy in T2/3); fluid leaking from vagina (membranes rupture); reduced or absent fetal movements after 24 weeks; fever > 38°C; signs of DVT (red, swollen, painful calf); chest pain or severe breathlessness; severe itch (especially palms / soles — cholestasis); seizure.
I'm bleeding in early pregnancy — am I miscarrying?
Not necessarily — but always check with provider. ~20-25% of pregnancies have some bleeding in T1; ~50% of those continue successfully. CAUSES: IMPLANTATION bleeding (6-12 days post-ovulation, light pink/brown, hours-days); CERVICAL changes (more vascular in pregnancy, can bleed lightly with intercourse or exam); SUBCHORIONIC HAEMATOMA (collection of blood between placenta and uterine wall — most resolve); MISCARRIAGE; ECTOPIC PREGNANCY. ANY BLEEDING IN T1: call Early Pregnancy Unit (UK) / OB (US). They'll likely check hCG trend and arrange transvaginal ultrasound. Heavy bleeding + severe one-sided pain + dizziness = same-day A&E (ectopic risk).
Is round-ligament pain normal?
YES. Affects most pregnant women, particularly 14-26 weeks. Round ligaments support the uterus; as uterus grows they stretch. PAIN: sharp pulling / aching sensation in groin or lower abdomen, often on movement, sneezing, sudden position change, or rolling over in bed. Usually one side (right common because of common uterine rotation), can be both sides. NORMALLY: brief (seconds to minutes), positional, no other symptoms. WORRY pattern: sustained pain (more than minutes), severe, with fever / bleeding / contractions. Eases with: slow movements, gentle stretches, warm bath, supportive maternity belt.
Why am I so breathless in pregnancy?
Several reasons. (1) Progesterone increases respiratory drive — you breathe faster and deeper, feels like breathlessness. (2) Growing uterus pushes diaphragm up from ~20 weeks (~5% lung volume reduction). (3) Blood volume up 50% — more oxygen demand. (4) IRON-DEFICIENCY ANAEMIA — very common; check ferritin. Most pregnancy breathlessness physiological. RED FLAG breathlessness: sudden onset, severe, with chest pain, can't lie flat, wakes at night gasping, with leg swelling. See /calculators/pregnancy-palpitations for the full cardiac differential.
Why am I so itchy in pregnancy?
Most itch is normal — stretching skin, hormonal. SOME itch is dangerous. NORMAL itch: belly, breasts, generalised mild itch from skin stretching. PUPPP (Pruritic Urticarial Papules and Plaques of Pregnancy): itchy rash on stretchmarks (~1% of pregnancies); third trimester; resolves after birth. RED-FLAG ITCH: SEVERE ITCH ESPECIALLY ON PALMS AND SOLES — characteristic of OBSTETRIC CHOLESTASIS (intrahepatic cholestasis of pregnancy, ICP). Affects ~1% of UK / Northern European pregnancies. Bile acid build-up; raises stillbirth risk if untreated. NEEDS BLOODS (bile acids, LFTs) and treatment (ursodeoxycholic acid). Severe palm/sole itch — same-day GP.
I have severe headaches — what do I do?
Most pregnancy headaches benign (hormonal, dehydration, tension, migraine). BUT severe headaches can signal preeclampsia, especially with: vision changes, upper-abdominal pain, sudden swelling, BP ≥ 140/90. PRACTICAL: paracetamol safe (not ibuprofen / aspirin in T3 unless prescribed). Hydration. Rest. If new severe / different / persistent / with red flags — same-day call to maternity unit. CHECK BP at home or community pharmacy. See /calculators/preeclampsia-risk.
What is reduced fetal movement and when should I call?
From 24 weeks, you should feel regular movements daily. RFM after 24 weeks: any reduction from your baby's normal pattern. NHS / RCOG Green-top 57: call maternity unit IMMEDIATELY, regardless of time of day. Don't wait until morning. Don't try to make baby move with sugary drinks / cold drinks / lying down before calling (these are post-call assessment tools, not delays). RFM can be first sign of placental issues. See /calculators/kick-counter.
Is severe nausea / can't stop vomiting a red flag?
YES — possible hyperemesis gravidarum (HG). Affects ~1-3%. RED-FLAG features: can't keep down ANY fluids for 24 hours; weight loss > 5% of pre-pregnancy weight; ketonuria; severe dehydration (no urine 12h, very dry mouth, dizzy); persistent vomiting > 4 weeks pregnancy. Treatment: IV fluids, IV antiemetics (cyclizine, ondansetron), possible admission. Not just 'bad morning sickness' — distinct condition needing treatment. See /calculators/puqe-score.
What's swelling that's a worry?
MILD ankle / foot swelling especially in T3 evenings is normal — gravity, fluid retention. WORRY swelling: SUDDEN, SEVERE, FACE/HAND swelling (especially overnight changes) — preeclampsia. ONE-SIDED LEG SWELLING with calf pain, red, warm — DVT (5x more common in pregnancy). PERSISTENT swelling not relieved by elevation. With these features — same-day call. Otherwise: elevate feet, compression stockings, walk regularly, stay hydrated (paradoxically reduces swelling — body holds less when well-hydrated).
What about heartburn / reflux?
Very common — affects ~50% of pregnancies, peaks T3. Progesterone relaxes the lower oesophageal sphincter; growing uterus pushes stomach up. STRATEGIES: smaller frequent meals; avoid spicy / fatty / acidic / large meals before bed; don't lie down for 1-2 hours after eating; sleep with head elevated (extra pillow); avoid trigger foods. MEDICATIONS: ANTACIDS (Gaviscon, Rennie) safe; H2 BLOCKERS (ranitidine — withdrawn in some places — famotidine) safe; PPIs (omeprazole) considered safe in pregnancy when needed. Severe heartburn doesn't = baby has hair (myth).
Constipation in pregnancy — what helps?
Common (~40%). Progesterone slows gut. Iron supplements worsen. STRATEGIES: increase fibre (fruits, veg, wholegrains); plenty of water (2-3 L/day); regular gentle exercise; respond to urges (don't delay); prune juice or pears. LAXATIVES: bulk-forming (Fybogel) first-line; lactulose safe; senna short-term if needed; PEG (Movicol) safe. AVOID: stimulant laxative dependence. Constipation + severe abdominal pain / blood / no bowel movement for many days = GP review.
What is symphysis pubis dysfunction (SPD) / pelvic girdle pain?
Pain in pubic area, hips, lower back, sometimes thighs. Affects ~25% of pregnancies. Pregnancy hormone RELAXIN softens pelvic ligaments; growing weight + uneven pressure cause discomfort. STRATEGIES: physiotherapy referral (women's health physio essential); pelvic-support belt; avoid standing on one leg; swim; pillow between knees at night; getting in/out of car keeping knees together. NICE supports physio. Often eases postpartum; some women have lasting issues warranting ongoing physio.
When is a fever a worry in pregnancy?
FEVER (38°C+) in pregnancy is more concerning than non-pregnant. RISKS: increased miscarriage risk; preterm labour; congenital effects (especially T1 — neural tube defects associated with hyperthermia). CAUSES: viral infection (cold, flu, COVID); UTI (very common in pregnancy — affects 4-7% of women); listeria (rare but serious); chorioamnionitis (uterine infection). ACTION: paracetamol for fever (safe in pregnancy); fluids; rest. CALL GP if: temperature ≥ 38°C; UTI symptoms (burning, urgency, smelly urine); flu symptoms (offered antivirals like Tamiflu free in pregnancy).
I'm experiencing severe mood changes — is this normal?
Antenatal anxiety / depression are common — affecting ~10-15% of pregnancies. SYMPTOMS: persistent low mood; loss of interest / pleasure; severe anxiety; panic attacks; suicidal thoughts; ANY symptoms lasting > 2 weeks affecting daily function. NICE recommends screening (PHQ-9 or EPDS) at booking and antenatal visits. NOT 'just hormones'. TREATABLE — talking therapy first-line (CBT, IPT free on NHS); SSRIs (sertraline first-line in pregnancy) when needed. Postpartum depression risk is higher if antenatal depression unaddressed. See /calculators/postpartum-mood-warning. ANY thoughts of self-harm = same-day GP / 999 / Samaritans 116 123.
