calcifying placenta?

Jacqueline
So I am 34 weeks and 3 days today. Yesterday I went to the OB for my growth scan/NST and they said they are sending me for a level two sono because my placenta seems to be calcifying a bit. She said it's normal at this stage for that to happen, but if it's normal, why are they sending me for a level two? It's ALWAYS something, ugh!!!!
