The experience of the coder. The complexity and size of the app. How bulletproof the app has to be, e.g. something to be run by a hundred tolerant people vs generally released to the public. The country the coder is living in.
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, youâd be right around the time a heartbeat is expected.
As a general rule, 5.5 to 6.5 weeks is the earliest time that your doctor will be able to detect a fetal heart beat by trans-vaginal ultrasound. In other words, about six weeks is the earliest stage where you can hear your tiny babyâs heartbeat with an ultrasound.etal heart dopplers can usually detect your babyâs heartbeat after about eight or nine weeks gestation, although it may be faint or inconsistent at that age. By 12 weeks into pregnancy, the doppler should consistently and audibly detect your babyâs heartbeat, allowing you to hear it sooner than you otherwise would.
