Worried FTM

Wondering if anyone else has gone through this. I’m 30w and 5d. My baby is measuring small (has been since around 20 weeks) and my fluid had been low my whole pregnancy. My doctor told me today that it’s because my placenta just isn’t doing it’s job. I was told that I’ll for sure be induced at 37 weeks but possibly sooner if things don’t improve. My baby has dropped down to the 14th percentile. She was in the 30th last month. I’m so worried because there’s literally nothing I can do but wait and hope all goes well, but I’m a wreck. 😞
