Hi, my wife is 23 weeks 5days pregnant and has undergone 1 USG on 03/02/2012. When is the date of 2nd USG? Also, 1st USG report says - BPD - 2.05cm, fl - 0.90 cm, AC - 6.44 cm, HC - 7.83 cm, Fetal Heart Rate - 156 beats/minute, Nucial Translucency - 0.09 cm corresponding to CRL of 71 mm. Is everything OK?
