A home fetal doppler like the SonoHealth HeartBeats is for reassurance and bonding, not diagnosis. If you can’t find the heartbeat or have any concern about your baby’s wellbeing, contact your healthcare provider rather than relying on what you hear at home.
What does the baby’s heartbeat sound like?
The fetal heartbeat is fast and rhythmic — usually a galloping, clip-clop, or fast train sound at a normal rate of 110–160 BPM. It is noticeably quicker than an adult heart rate, which is one of the easiest ways to confirm you’ve found the baby and not your own pulse.What is the whooshing sound?
A rhythmic whoosh-whoosh that matches your own pulse is usually the placental sound (sometimes called the uterine souffle) — blood flowing through the placenta and large vessels. It moves at your heart rate, not the baby’s faster rate. Hearing it often means you’re close; slide the probe slowly nearby to pick up the faster heartbeat.What are the swishing or thumping noises?
Sudden swishes, static bursts, or sharp thumps are typically fetal movement — the baby kicking or shifting against the probe. A regular, gentle thumping that isn’t the heartbeat can sometimes be fetal hiccups. These sounds are normal and harmless, though they can briefly cover the heartbeat until the baby settles.How do I tell my heartbeat apart from the baby’s?
Compare the rate. Your own pulse runs roughly 60–100 BPM, while the baby’s is much faster at 110–160 BPM. If a sound matches the pulse in your wrist or neck, it’s yours. For a step-by-step approach, see telling the maternal and fetal heartbeat apart.Tips for a clearer signal
Use enough ultrasound gel, keep the probe flat against the skin, and move it slowly with small tilts rather than sliding quickly. Lie back in a quiet room. Most early-pregnancy heartbeats are found low on the abdomen — see the how-to-use guide for placement.Related: How to Use Your Doppler · Normal Heart Rate Ranges · Maternal vs Fetal Heartbeat · Ultrasound Gel Guide
