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.
How early can an ultrasound detect a heartbeat? I am 25, and seven weeks pregnant with my first child. I just yesterday got an ultrasound, and no heartbeat was detected. Shouldn't there be a detectable heartbeat by now? This has me worried sick. The doctor said I should come back in a week for another ultrasound. What should I expect?
