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.
The baby's heart starts to beat at around 6 weeks. You may be able to hear â and see â your baby's heart beat for the first time when you're about 8 weeks pregnant if you have an early ultrasound exam. Otherwise, you'll probably first hear it with a fetal Doppler at a regular prenatal care visit. Your caregiver may be able to find it with the Doppler as early as 10 weeks, but it's more common to hear it at 12 weeks. How early the sound can be picked up depends on your baby's position in your uterus, your weight, and the accuracy of your due date.
