I went private and at 30 weeks my OB decided I was looking small. I then went off for scans for every 2 -3 weeks to check on the growth rate of the baby. He continually scanned between the 20-30th percentile. At 38 weeks my OB decided to induce me as the thinking was if my placenta wasn't working properly the baby would do better being fed on the outside. I was induced at 38 wks 4 days and bubby was born at 2.8kgs (6lb 4oz).

He did put on weight quickly after being born but it took until 6 months to reach the 50th weight percentile and at 8 months he has dropped under it again (I know there is also debate about how these percentile charts are constructed and what meaning they really have!).

I never got any feedback on if it was the placenta or just the baby but it all turned out well. My baby is happy and healthy and is getting into everything now. It is stressful when you are going through it though. If you are concerned I would get it checked out so you know exactly what you are dealing with. You can then relax and enjoy the rest of your pregnancy if all is ok. If the baby is on the smaller side you can then get all the information that you need about what might happen and any decisions you may have to make like induction etc.

Good luck!
