[|Human|] Hi, I am 28 weeks & 5 days as per LMP. Age of gestation is 30 weeks 1 day. Fetal measurements:  BDP = 7.69cm (corresponding 30 weeks 6 days) HC = 28.10cm (corresponding 30 weeks 6 days) AC = 26.68cm (corresponding 30 weeks 6 days) FL = 5.42cm (corresponding 28 weeks 5 days) Fetal weight is 1532+- 224grams AFI measures 17.8cm I am really worried because the doctor said the liquor is excessive
[|AI|]  Hi, I guess your concern is about accuracy of gestational age according to your imp and by ultrasound. Firstly, my straight forward answer is that gestational age according to your LMP is more accurate than your ultrasound gestational age. Because gestational age accuracy is changing according to each trimester of pregnancy. And it is more accurate if it is done in first trimester (it is from 1-12 weeks) and its accuracy will decrease in second trimester (13-28 weeks) and it is lowest in third trimester(29-40 weeks). So gestational age according to your LMP is most accurate. Secondly you have query about your excess liquor. Because the normal liquor ranging from 5-18 cm, and during this gestational age liquor is usually excessive, it decreases with time. With the above informative you can try out my suggestions-1. Don't worry, everything is alright.2. According to your ultrasound findings your baby is growing normally.3. If you are still worried then feel free to discuss with your treating doctor/gynecologist. Hope I have answered your query. Let me know if I can assist you further.
