What else can I help you with?
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.
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.
Can implantation occur three weeks after conception?
Implantation typically occurs 6-12 days after conception. Three weeks after conception would be around the time when a pregnancy test could give a positive result due to rising levels of the hormone hCG, but implantation itself would have occurred earlier.
Are there any changes in the inner and vaginal area in the earlier stages of pregnancy such as one week after conception?
When one is pregnant, one of the possible signs is a change in coloring to blue in this area.

Is measuring the femur bone in an ultrasound an accurate way to give you an estimated time of conception?
The best person to ask is the person doing the ultrasound. Having said that here are a few guidelines. Ultrasounds can give you a fairly accurate time for the length of the pregnancy. Before 10 weeks the measurement taken is crown-rump length, from the top of the head to the bottom of the spine. This is accurate to within 3-4 days. After about 12 weeks several measurements are taken, head circumference, head diameter and abdominal diameter as well as femur length and the results are plotted on a graph to compare with the estimated length of pregnancy. The earlier the measurements are taken the more accurate they are in assessing the length of the pregnancy.
