IUGR management

Anybody else here who has had or has a case of IUGR (intrauterine growth restriction)? In my first pregnancy, my daughter was 3 - 4 weeks behind her dates, and was born at 37th week with moderately low birth weight (4.5 lbs), though she was otherwise healthy. I had barely gained 19 lbs (I should have gained at least 28 lbs cuz my BMI was already low). I am not gaining enough weight in my 2nd pregnancy too, I am 17 WK 5 days with no weight gain so far (in fact I lost about 11 lbs) during first trimester due to nausea. Pls share how did your doc manage the IUGR - gave aspirin, or protein supplements, or any other treatment?
