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.
When will I be able to hear my baby's heartbeat? At around 10 weeks, a Doppler ultrasound will allow you to hear your baby's heartbeat for the first timeâbut her heartbeat will already be visible on ultrasound by the time you are about six weeks pregnant. (To see what your baby's heartbeat looks like at six weeks, check out Drs. Doubilet and Benson's site: yourdevelopingbaby.com.) The first detection of the baby's heartbeat has both medical and emotional significance, says Dr. Doubilet.
