What does the fetal heartbeat sound like?
The fetal heartbeat is fast and rhythmic, usually 110–160 BPM, with a distinctive “galloping horse” quality. It is noticeably quicker than an adult heart rate, and the digital BPM display on the HeartBeats™ Fetal Doppler helps confirm what you are hearing. If the number on screen sits in the 110–160 range, you have almost certainly found your baby.How is my own pulse different?
Your maternal pulse is slower — typically 60–100 BPM — and steadier. If the display shows a rate in that lower range, you are most likely picking up your own blood flow, not the baby. Reposition the probe and search for the faster signal. The normal heart rate ranges page breaks this down further.What is the whooshing sound I keep hearing?
A slower, windy “whoosh” that matches your own pulse is usually the placental sound — blood moving through the placenta. It is normal and even reassuring, but it is not the heartbeat. Keep moving the probe slowly until the rhythm speeds up into the rapid fetal beat.Why does the rate matter more than the volume?
A louder sound is not necessarily the baby. Because the maternal pulse and placental flow can be strong and close to the probe, rate is your most reliable guide — always trust the BPM and the galloping quality over how loud a sound is. Our how it works page explains the science behind these sounds.Tips for getting a clear fetal signal
- Use plenty of water-based ultrasound gel for good contact — see our gel guide.
- Start low, just above the pubic bone, and move slowly in a wide search pattern.
- Rest a few minutes if you have just been active, since an elevated maternal pulse is easier to confuse with the baby.
- Be patient before 14 weeks — difficulty usually reflects positioning, not a problem.
A home doppler is for reassurance and bonding only. Finding (or not finding) a heartbeat does not confirm or rule out your baby’s wellbeing. Use it gently and occasionally.
