Often detected on the lower left or right side as the fetus grows upward.
32–40 weeks
Commonly heard on the upper or lower sides of the belly. Note: Often opposite the side of fetal movement.
Fetal Heart Rate Reference
A healthy fetal heart rate typically ranges from 120 to 160 beats per minute.
Before 20 weeks

Helpful Answers
FAQs
Get expert guidance on the BabyNera HeartEcho™ fetal doppler. Our resources cover FDA-cleared safety standards, the clinical advantages of 2.0 MHz frequency technology, and precision heartbeat detection starting from 9 weeks. Engineered for professional-grade reassurance and locally stocked in the USA and Australia for rapid, dependable delivery.
Is the BabyNera HeartEcho™ fetal doppler FDA-cleared and safe?
Yes. Safety is our foundation. The BabyNera HeartEcho™ is FDA-cleared (510(k) compliant) and CE Marked. It utilizes low-power, non-invasive ultrasound technology that is radiation-free. It is engineered for safe, short-duration bonding sessions and is trusted by over 120,000 parents for peace of mind between clinical prenatal visits.
How early in my pregnancy can I hear a heartbeat with a home doppler?
Most users can detect a clear heartbeat starting at 9 to 12 weeks. While every pregnancy is unique, our Early Detection Algorithm is specifically tuned to identify faint first-trimester signals. By 12 weeks, over 98% of BabyNera users report a stable, audible heart rate.
What is the recommended frequency for using the BabyNera fetal doppler?
While our technology is safe and low-intensity, we recommend using the doppler for short, joyful bonding sessions a few times a week. It is a reassurance tool and should not replace regular kick-counting or professional medical checkups in the third trimester.
Can I use the HeartEcho™ if I have an anterior placenta or a higher BMI?
Absolutely. This is where the BabyNera 2.0 MHz technology excels. Unlike standard 3.0 MHz monitors that struggle with depth, our 2.0 MHz probe offers deeper penetration (up to 24cm). This makes it the clinical standard for finding signals through placental noise or additional tissue where other devices often fail.
Why is the 2.0 MHz probe superior to common 3.0 MHz models?
While 3.0 MHz probes remain common, 2.0 MHz is increasingly recognized in 2026 as the preferred frequency for deeper signal reach. BabyNera’s 2.0 MHz probe is designed for more effective heartbeat detection—especially in cases like anterior placentas or early pregnancy—delivering a clearer and more stable listening experience.
Many parents also find lower-frequency probes easier to use at home, as 3.0 MHz can be more position-sensitive and less consistent when reaching deeper signals.
How do I distinguish the baby’s heart rate from my own pulse?
A baby’s heartbeat sounds like a fast "galloping horse" (120–180 BPM), while your pulse is a slower "thump" (60–100 BPM). The HeartEcho™ makes this easy by displaying the exact BPM on the high-contrast OLED screen, helping you visually confirm the baby’s heart rate instantly.
How accurate is the digital HeartEcho™ BPM display?
The HeartEcho™ utilizes Medical-Grade DSP (Digital Signal Processing) to provide an accuracy of ± 2 BPM. This technical precision reduces "signal jumping," ensuring you get a steady and reliable reading of your baby's vital signs compared to non-digital alternatives.
Does the set include ultrasound gel, or is it sold separately?
Your BabyNera Exclusive Set is a complete, ready-to-use solution. Every order includes the HeartEcho™ device, the 2.0 MHz probe, a full-sized bottle of professional ultrasound gel, and a velvet travel pouch. Everything you need for clear sound conduction is included in the box.
How fast is shipping for US and Australian orders?
