In my opinion the scan report is absolutely normal. In a 2nd and 3rd trimester ultrasound the parameters of baby like BPD(biparietal diameter), FL(femur length), AC(Abdominal circumference) are taken. All these are corresponding to one another around 21-22 weeks. And the AFI(amniotic fluid index) is an indicator of liquor and is adequate. Usually placenta is implanted over the anterior or posterior or funds of uterus and here it is anterior, and the implantation is normal. There are no blood clots associated with it or any blood collection which is suggested by no blood clots, no chorionic haemangioma etc. The cervix is closed and EFA(estimated fetal weight) is around 370+/-50 GMS. Fetal heart rate is 142 /min which is also good. Expected date of delivery(EDD) is June 30 +/- 1 week. Overall the ultrasound report is normal. Maternal abdomen normal means mother abdomen is also normal. Hope this helps. Best regards... Chat Doctor.  </s>
