My wife told her doctor she didn't know when her last mp was, so he sent her for an ultrasound! She lied, we just wanted 2 get an early ultrasound, and it was exact 2 the day and that was at 5 weeks 4 days! Our 1st baby measured within 5 days thru the entire pregnancy, and that was as early as 8 weeks and as late as 26!

How many ultra-sounds are safe during pregnancy?

There is no proved data that ultrasounds are hazardous to fetus. However, in routine practice, three ultrasounds are done one in each trimester of pregnancy. These are considered totally safe by all the gynaecologists. Some ladies might have to undergo through more ultrasounds if some fetus anomaly is suspected. There is no evidence that these ultrasounds were harmful to fetus. So ultrasound during pregnancy is totally safe. The number of ultrasounds required are decided by the gynaecologists.

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.
