My dating scan is wrong why

Rated 3.97/5 based on 668 customer reviews

For transvaginal ultrasound you can have an empty bladder Dating scans are usually recommended if there is doubt about the validity of the last menstrual period.

For example if you a tiny sac can be seen in the uterus, but the baby and its heart beat may not be detected yet.

If you have any questions about this, please feel free to talk to your sonographer or doctor about it.

Gut feeling this time says boy (it said girl last time, and I have a beautiful 16 month old daughter).

Wishing you all a lovely day x My understanding is it can only be wrong through two factors a) you do it too early (before 9 weeks) and male DNA does not show up, so you get a false female result- if you are definitly past 9 weeks (which I assume you are being on this board) then that is not a possibility so you're good on that count B) contamination of sample: taking a sample in a room with male DNA or not washing hands after touching a male, or a male handling the sample equipment can cause a false male result. So if the top one doesn't apply to you then you have a little girl :) congrats!!!!!

Of course there is the chance they misread or wrote down the wrong result but I highly doubt it.

Ultrasounds performed during the first 12 weeks of pregnancy are generally within 3 - 5 days of accuracy.

As the baby gets bigger, it starts to express its individual growth potential.

the baby and its heart beat can be detected relatively easily with trans-abdominal and trans-vaginal examination.

This is presuming that the pregnancy is actually at this stage of development.

Ultrasounds performed after 22 weeks gestation cannot be used to estimate the due date of the baby because the size no longer reflects the age very well.

Even average babies can differ by up to 2 to 3 "weeks of growth";.
