When it says that an ultrasound is most accurate at 12 weeks does that mean gestational age or the time since LMP?

The earlier it is the more accurate it is whether from conception or from LMP, but if you say 12 weeks you mean from LMP.

It is not likely, the most you would see is the gestational sack. The heartbeat cannot even be detected until week 5.

The ultrasound at 18 weeks is about 90 to 95 percent accurate. It there is a flat place between the legs it means it is a girl if there is something hanging it means it is a boy.
What's the difference between galmp and gaedd when an ultrasound is performed?
GA is gestational age which is how far pregnant you are. LMP is last menstrual period, which is the date of the first day. EDD is estimated dte of delivery (40 weeks from the LMP) The EDD may be changed if the ultrasound gestational age differs from the age by LMP by a lot.
What is visible on an ultrasound at 6 weeks?
At 6 wks pregnant, on ultrasound, you can see the gestational sac ( the home of the baby). Unless you have an endovag ultrasound, then you can see a very small fetal pole and a small heart beat. It is very hard to see anything at that early of pregnancy.

When did you conceive Not sure of first day of LMP but last day was 21407 ultrasound done today 32107 says 5 weeks gestational age?
Because of the way that gestational ages are calculated, a pregnancy called "5 weeks gestational age" was conceived during sex that happened about three weeks ago, so you probably conceived around the first of March. That date makes sense with your best guess of your LMP date as well.
How accurate is the ultrasound due date?
They are accurate within 2 or 3 days. But this does not mean that you will have the baby on your due date. Babies can be born any time between 37 and 42 weeks. That is what midwives are taught anyway. With my first my ultrasound said I was due 10 days after my period date but my husband had been away on a trip form the day after conception! Second time around the ultrasound agreed completely, and showed twins. (now 16) == Your last known period date or the date of conception is a better predictor....as all babies are different & you may have an extrememly large or an extremely small baby for it's gestational age, and when compared against babies in the "norm" the due date could be way off.
How accurate is an ultrasound if you do not remember your period?
If you do not remember the date of your last period you can have an ultrasound to determine your due date. More than one ultrasound throughout your pregnancy may be required because ultrasounds are not always accurate. They could be out as little as a couple of days by a matter of weeks.
Is the EDD given to you on your scan date from your LMP or by the date of conception?
EDD is ESTIMATED. If done by scan is 38 weeks from conception. An EDD is based on the LMP (last menstrual period) and not the date of conception. The ultrasound measurements are comparing the baby to the expected size of other babies at the same gestational age. The earlier the ultrasound is done in the pregnancy, the more accurate it will be. Hope this helps! Dr. B.
