• Usage Timeline: Fetal dopplers are typically designed to detect heartbeats starting around the 10th to 12th week of pregnancy, though it can sometimes be difficult to locate the heartbeat early on.
• Limitations: Home monitors are for reassurance and should never replace professional prenatal care or regular checkups with a doctor or midwife.
• Concerns: Difficulty finding a heartbeat with a home doppler can cause unnecessary anxiety, as position, gestational age, and maternal movement can interfere with the signal
