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.
If the baby's big enough you can hear it between 12 and 13 weeks mine was still too small so I will hear it at my next appointment where I will be about 14-15 weeks along.You can still see the heartbeat on an ultrasound as early as 5 weeks.
