Bleeding in Early Pregnancy

Clinical Scenario

Natasha Paine, 30, books an urgent video consultation for vaginal bleeding. She is approximately 11 weeks pregnant with a planned and wanted pregnancy. She noticed light vaginal bleeding this morning — bright red, no clots, no pain. She has a 3-year-old son born via normal vaginal delivery. She has asthma but is otherwise well. She is visibly anxious and tearful on camera, asking "am I losing the baby?"

What This Case Tests

Assessing bleeding in early pregnancy via remote consultation; differentiating threatened miscarriage from ectopic pregnancy and other causes; arranging urgent same-day Early Pregnancy Assessment Unit (EPAU) referral; providing compassionate care while managing clinical urgency; delivering honest information about prognosis without removing hope.

Common Mistakes Trainees Make

The three most common mistakes are: offering premature reassurance ("light bleeding is very common and usually fine") before excluding ectopic pregnancy — which is a life-threatening emergency, failing to arrange same-day assessment (all bleeding in early pregnancy requires EPAU assessment within 24 hours), and focusing exclusively on the clinical management without addressing Natasha's emotional state — she is terrified of losing a wanted pregnancy.

The Consultation Challenge

This is an acute emergency presentation that tests your ability to manage clinical urgency and emotional distress simultaneously. Natasha is asking you a question you cannot answer: "am I losing the baby?" The honest response is that you don't know yet, and the priority is getting her assessed urgently.

Start with a focused assessment. On video, observe her general appearance: does she look well, pale, or unwell? Is she in pain? Then take a rapid history: when did the bleeding start, how much (pad count, colour, clots), any abdominal pain (location, severity, character), any dizziness or faintness, when was her last scan (has viability been confirmed?), any previous miscarriages, and her blood group (Rhesus status matters for Anti-D).

The critical differential is between threatened miscarriage (bleeding but pregnancy continues) and ectopic pregnancy (pregnancy outside the uterus — life-threatening). Ectopic red flags: unilateral lower abdominal pain, shoulder tip pain, dizziness/syncope, haemodynamic instability. If any of these are present, this is a 999 emergency, not an EPAU referral.

If Natasha is haemodynamically stable with light painless bleeding, the most likely diagnosis is threatened miscarriage. Approximately 25% of pregnancies have some first-trimester bleeding, and of these, about 50% continue to a healthy outcome. However, you cannot confirm viability without an ultrasound — which is why EPAU assessment is essential.

Arrange a same-day EPAU referral. Explain clearly what will happen: she will have a transvaginal ultrasound to check the pregnancy location and viability. The scan will give a definitive answer. Explain the timeline — she should be seen today or tomorrow at the latest.

Address her emotional state directly. "I know this is terrifying, and I wish I could tell you right now whether everything is okay. What I can tell you is that bleeding in early pregnancy is common — about 1 in 4 pregnancies — and in many cases the pregnancy continues normally. But we need a scan to know for sure, and I'm arranging that urgently for you."

Provide practical interim advice: rest (though no evidence bed rest prevents miscarriage), attend A&E if bleeding becomes heavy (soaking a pad in an hour), if she develops severe pain, or if she feels faint. Take paracetamol for pain if needed. Avoid intercourse until assessed.

Time check: Spend the first 4 minutes on the focused clinical assessment and red flag screening. By minute 6, make the EPAU referral decision and explain the plan. Address Natasha's emotional state between minutes 7-9. Use the final 3 minutes for safety netting, interim advice, and Rhesus status consideration.

How Examiners Mark This Case

Data Gathering and Diagnosis: Examiners assess whether you take a focused history covering: bleeding characteristics (amount, colour, clots, duration), associated symptoms (pain — location and character, dizziness, syncope), pregnancy details (gestation, planned/unplanned, previous scans confirming location), obstetric history, and relevant medical history (Rhesus status). Critically, they look for active screening of ectopic red flags — a trainee who does not ask about unilateral pain, shoulder tip pain, or haemodynamic stability will lose significant marks.

Clinical Management and Medical Complexity: Examiners expect an urgent same-day EPAU referral as the clear management priority. They look for knowledge of what the EPAU assessment involves (transvaginal ultrasound, serum hCG), when to escalate to emergency attendance (ectopic features, heavy bleeding, haemodynamic instability), consideration of Anti-D for Rhesus-negative women, and appropriate interim safety netting advice. A trainee who offers reassurance without arranging assessment, or who sends Natasha to A&E unnecessarily for stable threatened miscarriage, will score poorly.

Relating to Others: Heavily weighted. Examiners assess whether you acknowledge the emotional impact of this situation, whether you answer Natasha's question ("am I losing the baby?") honestly without removing hope, and whether you provide clear, practical information that helps her feel supported between now and the scan. The balance between empathy and clinical efficiency is the core challenge.

Example Opening

Strong opening: "Hello Natasha, I can see you're really worried. Let me start by saying you've done the right thing calling us urgently. I'm going to ask you some important questions so I can work out the best next step for you and the baby."

When she asks "am I losing the baby?": "I understand why you'd ask that, and I wish I could give you a definite answer right now. What I can tell you is that bleeding in early pregnancy is actually quite common — about 1 in 4 pregnancies — and in many cases everything turns out fine. But we need an ultrasound scan to know for sure, and I'm going to arrange that for you today."

Avoid: "Try not to worry — it's probably nothing." (Minimises her concern and offers reassurance you cannot back up without investigation).

How This Appears in the SCA

Bleeding in early pregnancy is a high-stakes SCA case that tests your ability to manage clinical urgency while providing compassionate care. The examiner assesses whether you can exclude ectopic pregnancy (a life-threatening emergency), arrange appropriate urgent referral, and support a frightened patient — all within a remote consultation.

Key Statistic

First-trimester vaginal bleeding occurs in approximately 25% of pregnancies. Of those with a threatened miscarriage (bleeding with a closed cervix and confirmed intrauterine pregnancy), approximately 50% will continue to a successful outcome. Ectopic pregnancy occurs in approximately 1 in 80 pregnancies and is the leading cause of maternal death in the first trimester.

Frequently Asked Questions

How do I exclude ectopic pregnancy in a remote consultation?

Ask directly about ectopic red flags: unilateral lower abdominal pain (especially if sharp and persistent), shoulder tip pain (diaphragmatic irritation from intra-abdominal bleeding), dizziness or feeling faint on standing, and any collapse. If any are present, this is a 999 emergency. If the patient is stable with painless bleeding, ectopic is less likely but cannot be excluded without imaging — this is why EPAU referral is essential regardless.

What is the prognosis for threatened miscarriage?

If a viable intrauterine pregnancy is confirmed on ultrasound with a fetal heartbeat, the chance of continuing to a successful outcome is approximately 90-95%, even with bleeding. If viability has not yet been confirmed, the outcome is uncertain until the scan. Approximately 50% of women with first-trimester bleeding will continue to have healthy pregnancies. Present this honestly without guarantees.

When should I advise the patient to go to A&E instead of EPAU?

Advise A&E attendance if: bleeding becomes heavy (soaking a pad in under an hour), there is severe or worsening abdominal pain, the patient feels faint or collapses, or there are signs of ectopic pregnancy. For stable, light bleeding without pain, EPAU is the appropriate referral — A&E does not have the ultrasound expertise for early pregnancy assessment and may create unnecessary delay.

Should I consider Rhesus status in early pregnancy bleeding?

Yes — Anti-D prophylaxis should be considered for Rhesus-negative women with bleeding after 12 weeks gestation. Before 12 weeks, Anti-D is recommended if the bleeding is heavy, if there is associated pain, or after surgical intervention. Check and document Rhesus status. If the patient's blood group is unknown, the EPAU will assess this. Mentioning Rhesus status demonstrates thorough Clinical Management.

What interim advice should I give while awaiting the EPAU appointment?

Advise rest but clarify that bed rest does not prevent miscarriage (this is a common misconception). Avoid intercourse until assessed. Take paracetamol for pain if needed. Monitor bleeding — note pad count and any clots. Attend A&E if bleeding becomes heavy, pain develops, or she feels faint. Avoid aspirin and NSAIDs. Provide the EPAU contact number for any concerns before the appointment.
