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.
Hearing or seeing your babyâs tiny heart beating for the first time is an exciting moment. Your baby's heart starts beating when you're six weeks pregnant. Around the time of your dating scan, your babyâs heart is beating between 110 times and 160 times a minute. Thatâs about twice as fast as your heartbeat. You may also hear your babyâs heartbeat at one of your antenatal appointments. Your midwife is unlikely to listen for it while youâre still in your first trimester, as it can be hard to pick up at this stage. After your dating scan, the next time you hear your babyâs heartbeat may be during your 16-week appointment with your midwife.
