Brief Answer: Seek an obstetrician, no worries Detailed Answer: Thank you for asking! These are the fetal growth measurements of your baby. These all are intended to keep the age , weight and growth profile of a baby. These are done in 2nd trimester onwards and are accurate from 12 to 22 weeks of gestation..Before that Crown rump Lengths CRL and MSD mean sac diameters are the keys. BPD means Biparietal diameter i.e distance between two sides of the ead where parietal bone lies( Area just above the ear). HC is head circumference.AC is abdominal circumference. 10th percentile is to correlate the baby growth to other babies for example out of 100 babies your baby is larger than 10 other babies and smaller than 90 other babies in comparison. of the same gestational periods. A fetus is considered normal if they are between 10th and 90th percentile. So from all these mentioned reports you provided, the recent scan shows that you have a healthy baby, averaging 82 grams /2.9 ounces / 0.18 pound with age of 17 weeks and 3 days and good looking. The only issue which might be trouble in future is the decreasing percentile. The fetus is on the lowest limit of percentile chart of normal. A single more percentile drop will put in in growth retardation criteria.Stay in touch with your obstetrician and let him devise a complete plan to keep your baby out of trouble zone. So far so good. I hope it helps.Take good care of yourself and your baby.May the odds be ever in your and your baby's favour. Regards S Khan

Brief Answer: Sorry for the inconvenience, Correlation advised Detailed Answer: Thank you for asking! I meant to say the dimensions you mentioned should be at the age of 17 weeks gestation.Now that you mentioned your gstation of 33 weeks, i am afraid your baby is severely underweight and small for gestation and needs a bit workup for intrauterine growth retardation and intra uterine neonatal resuscitation. Third trimester needs to be addressed by an expert obstetrician. Here comes the importance of complete clinical correlation with a detailed history , physical examination and a complete clinical correlation.As a simple ultrasound out of the context can be misleading especially when it is at the small for gestation issues. I hope you see that in aright perspective. Regards

Brief Answer: Hope for the best Detailed Answer: Thank you for getting back to me! As i said it is a severe small for gestation and needs a lot of care and monitoring by neonatologists and obstetricians. And being on 10th percentile considering once being on 3rd is an improvement. But the kid needs a lot of care and if i write it thousand times it still wont compensate the importance of monitoring. I wish i could do any more in your case. may the odds be ever in your favour.
