Caliper placement for CRL measurement should correspond to the longest straight line from top of fetal head to rump.At 5+6 my baby measured 2.3mm so I would say at plus 4mm baby is measuring over 6 weeks. These measurements aren't totally accurate early on anyway, so it all seems fine xx. This says anything from 5mm to 12mm is normal for 7 weeks so there is a massive discrepancy in growth.Crown Rump Length: Gestational age = 6 weeks plus (CRL x days).

The gestational age is confirmed by CRL measurement. The gestational age can be calculated by using the attached chart to look up the estimated gestation. When the gestational age based on CRL is within 7 days of that calculated from the LMP, we consider the LMP to be reliable, andAll charts generated dates significantly different to IVF dates (P < 0.0001 all comparisons). Thus we generated a new reference chart, The Monash Chart, based on a line of best fit describing crown-rump length across 6 + 1 to 9 + 0 weeks of gestation (true gestational age) in the IVF singleton cohort. The length of the fetus from the crown (top of the head) to the bottom of the buttocks (the area above where legs begin) is called as Crown Rump Length (CRL). It is measured from 6 - 13 weeks of pregnancy. In this online CRL calculator, you can find the crown rump length for the number of weeks.
