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.
Your baby's heart beats between 110 times and 160 times per minute. You may also hear your baby's heartbeat at one of your antenatal appointments. Your midwife is unlikely to listen for it while you're still in your first trimester, as it can be hard to detect at this stage. After this scan, the next time you'll hear your baby's heartbeat will probably be during your 16-week appointment with your midwife.
