when can you hear heartbeat on ultrasound
A: On transvaginal ultrasound, you can usually see the heartbeat by about four weeks after conception. In obstetrics, we traditionally count weeks from the last period. For a woman with 28-day cycles, a month pregnant is about two weeks after conception, and you would not expect to see a heartbeat. But by a month after conception, youâd be right around the time a heartbeat is expected.
