Pregnancy Follow-Up Scans — Returning for Growth and Wellbeing
One scan is a snapshot. A pregnancy followed over time is a story — each visit builds on the last, from your earliest scan to third-trimester growth checks.
- Self-referral — alongside, never instead of, your NHS antenatal care
- Findings discussed at every visit — written report usually within two hours
- Same clinic, same records — every scan compared with your previous ones

Why come back for follow-up scans in pregnancy?
Because trends tell you more than single measurements. Many women see us once for reassurance and that is exactly right for them. But when scans are repeated through a pregnancy — each one anchored to the last — your sonographer can see whether things are stable, improving or shifting, rather than judging one moment in isolation. Where a repeat is clinically indicated, growth scans are usually advised at 2–4-week intervals; your sonographer will tell you if that applies to you and your report will state it clearly.
Follow-up scanning with us runs alongside your NHS antenatal pathway — it never replaces your midwife appointments or your NHS 12-week and 20-week scans, and anything significant we find is reported in writing so your midwife or obstetrician can act on it.
How the scans build on each other
- 1
Early pregnancy scanEstablishes the pregnancy’s location and confirms the heartbeat. See our early pregnancy scan.
- 2
Dating scanRefines your dates — the anchor every later growth assessment is measured against. See the dating scan.
- 3
Gender scanOften chosen for the reveal — and another opportunity to review your baby’s developing anatomy. See the gender scan.
- 4
Growth & wellbeing scansThird-trimester checks of growth, fluid and blood flow — repeated at 2–4-week intervals where indicated. See the growth scan.
Why trends matter more than single measurements
A single scan gives you a snapshot; a pregnancy followed over time gives you a story. Serial growth scans in particular are about trends rather than isolated measurements. One tummy measurement on the 20th centile is not concerning in isolation — but a downward trajectory across successive scans is, and that is exactly the kind of change a one-off scan cannot show.
We usually advise 2–4-weekly growth intervals when there is a clinical reason — reduced bump measurements at midwife checks, maternal risk factors, or a borderline centile that needs context. That interval balances real biological change against normal measurement variability: scan too soon and you are chasing noise; too late and you risk missing a meaningful shift.
This is a generalised pattern from our pregnancy casebook, not an individual case. Every pregnancy is different — findings are always discussed with you at your scan, and anything significant is reported in writing for your midwife or obstetrician.
Some situations need your maternity unit, not an appointment with us. If you notice reduced or changed baby movements, contact your midwife or maternity unit straight away — do not wait, and do not book a scan first. For heavy bleeding, severe abdominal pain, severe headache or visual disturbance, fluid loss, or feeling seriously unwell, call your maternity triage line immediately or 999. A private scan is never a substitute for urgent maternity care.
