Baby stomach 10 days smaller?

firt time mommy here

Anyone have experienced this. I am 34 weeks pregnant & the dr said my placenta is small therefore the baby's stomach is small & I have to be monitored to see if the placenta is preventing the baby from growing. He said the rest of the baby's body parts are normal size its just the stomach that is measuring 10 days smaller.

Anyone have this happen? What was the outcome?
