IUGR?

Any of you ladies been diagnosed with Intra Uterine Growth Reduction (IUGR)? I'm 29 weeks and looking a lot more like 19 weeks. 😐 Seeing my OB/GYN in the morning after GP has told me I should be referred for scan to ensure baby is actually growing because I am growing at a very slow rate. Currently 6cm behind growth rate expected for this stage of pregnancy (I should note, I am a small woman - 5'4, 116lb pre pregnancy and only gained 14lb so far).
