The HeartBeats™ is best for reassurance and bonding between prenatal appointments — not for monitoring or diagnosing. When in doubt about your pregnancy, always call your provider first.
What to Expect
When you’ll first hear it: Most parents hear the heartbeat for the first time around 12–14 weeks. Before 12 weeks, the baby is still very small and positioned low behind the pubic bone, making it hard to detect with a home doppler. Don’t worry if you can’t find it early — this is normal. What it sounds like: Your baby’s heartbeat sounds like a fast, rhythmic “whoosh-whoosh” — much faster than your own heartbeat. Normal fetal heart rate is 120–180 BPM. Your own pulse is 60–100 BPM, so if the reading is slow, you’re likely hearing yourself. How long it takes: In the second trimester, most sessions take 2–5 minutes. Earlier in pregnancy (12–14 weeks), plan for 5–10 minutes of gentle searching.Step-by-Step: Your First Session
- Lie flat on your back with a small pillow under your hips
- Apply gel generously — ultrasound gel (or plain aloe vera) to your lower abdomen
- Start low — just above your pubic hairline, not at your belly button
- Angle the probe downward toward your pelvis at about 30–45 degrees
- Move slowly — about 1cm at a time. The signal zone is small early on
- Watch the BPM display — fetal heart rate should read 120–180 BPM
- Be patient — it may take a few sessions to find the right spot consistently
What You’ll Hear
| Sound | What It Is | BPM Range |
|---|---|---|
| Fast “whoosh-whoosh” | Baby’s heartbeat ❤️ | 120–180 BPM |
| Rushing, slower sound | Placenta / blood flow | Follows your pulse |
| Slow rhythmic beat | Your own pulse | 60–100 BPM |
| Clicks and bumps | Baby moving | Irregular |
Trimester-by-Trimester Guide
First Trimester (Weeks 1–12) Detection with a home doppler is unreliable before 12 weeks. Your baby’s heart has been beating since around week 6, but it’s too small and too low for a home doppler to reliably detect. Wait until at least 10–12 weeks before trying, and have realistic expectations. Second Trimester (Weeks 13–27) This is the sweet spot for home doppler use. Detection becomes reliable from about 14–16 weeks. Heart rate typically ranges from 120–160 BPM. You’ll start hearing the heartbeat clearly and consistently. Third Trimester (Weeks 28–40) Easy to detect. Baby is large and the heartbeat is strong. Heart rate typically ranges from 110–160 BPM. You’ll also start hearing more movement sounds. Continue using kick counts as your primary check-in method in the third trimester.Tips from Parents Who Use It
- Try right after a meal — baby is often more active
- A slightly full bladder can help in early pregnancy (lifts the uterus)
- The heartbeat sounds different from what many people expect — trust the BPM number more than the sound
- Your baby moves — if you lose the heartbeat, they probably shifted. Reposition slightly
- Try different times of day; baby has active and quiet periods
The Most Important Safety Rule
A home doppler is a bonding tool. It is not a clinical monitor. Finding a heartbeat does not mean everything is fine — and not finding it in a short session usually doesn’t mean something is wrong. When in doubt: call your provider.When to Call Your Provider
- You cannot find the heartbeat after 16 weeks with consistent effort
- You previously found the heartbeat and now can’t
- Baby’s movements feel reduced
- You have any pain, bleeding, or unusual symptoms
- You’re simply unsure or worried
