How accurate are dating scans at 14 weeks Teen adult phone chat
The earlier the ultrasound is done, the more accurate it is at estimating the baby's due date.Ultrasounds performed during the first 12 weeks of pregnancy are generally within 3 - 5 days of accuracy.) the fetus is clearly seen on trans-vaginal ultrasound and the heart beat can be seen at this early stage (90 to 110 beats per minute under 6 to 7 weeks, then 110 to 200 beats per minute as the baby matures).
) The midwife explained to me why there was the discrepancy, and that is is fairly common so put my mind at rest. I think it will be nearer the 11th and that the baby was just measuring big at the time of the scan.
I was charting my temperature and other ovulation indicators so I thought I knew when I conceived but all 3 scans so far have come out with similar dates to each other but different to my calculated date, they are using their dates so I am too !!
