Dear Suba,
I have to say sorry that your Dr./radiologist has put you in puzzle without describing anything in detail. I am a little upset that ultrasonography is performed but explanation is inadequately provided. For any simple person medical terms mean nothing, you have written down the terms out in your message and I believe many won't understand here.
Of three major issues two of them couls be discussed and third one would not be easy to discuss by letter.
1. IUGR, I am surprised here to note that your case is treated like IUGR-Intra Uterine Growth Retardation, this condition is usually identified in third trimester. Also the estimated date vary for given pregnancy from ultrasound to ultrasound as long as it is giving +/- 2 weeks difference it's considered OK and that's because each baby developes differently. Here I have problem your estimate is 17-18 weeks how could a radiologist give you an estimate with range and not precise gestation. I mean it would estimate like 17 weeks 6 days or whatever it is, an ultrasonogrpahy won't estimate in range like somewhere between 157 weeks to 18 weeks, that's unacceptable statement to me. If your gestation lags 2 weeks behind from your last ultrasound perhaps you should not worry and should not think on IUGR. Neverthelss, IUGR is not terrifying, don't get too upset some babies grow better after birth, so don't worry too much.
2. Oligohydramnios, this is a term when there is scanty amniotic fluid. The blame would go partly to your living style. You must drink at laeast 8-10 glasses of water each day, no matter if that's difficult for you to due to some m/s. YOu have got to try this out. Keep your carbohydrates diet on normal front. This is likely to re-establish fluid to it's normal level. I have seen cases where they found to have excess fluid and in next day back to normal and many who suffer from low quantity fluid and then with rest, water and good carbohydrates they come back to normal fluid level so get good habit of water and carbohydrate intake.
3. Fetal hypoxia is a little difficult thing to explain at least to me by letter. Let me ask you a few question, are you a second hand smoker or second hand alcoholic person? If you answer yes to this question then it would be easier. Otherwise all I could say is stay away from people who smoke and drink.
What's important is second trimester u/s is for anamoly and there all looks normal to you. There are many things one can not know by ultrasound and many things can be scary although in real it's not the case. So take a copy of report to your OB/GYN here in US and see what advice does he/she offers you.
Watch out with your water intake and rest well. Eat healthy and nutritious diet. Typical vegetarian girls are likely to deliver underweight baby. So if you are not going to get on to some chicken, poulty then there is very little we could do about it. But may be when you are back see a dietician who will guide you on diet to overcome small size baby if that's what trouble is. I bet your Dr. will want to have an ultrasound around week 24 and week 28 to see that fetus development is meeting to expected gestation.
keep me updated. You are in prayers.
