Calcifying plqcenta

I went in last friday(4Jan) for ultrasound (36w4d). Doc said my placenta is busy calcifying and he wants to see me again Thursday (10Jan)(37w3d) he also said he MIGHT need to induce me then.. since yesterday afternoon (7Jan ) my baby girl hasnt been kicking/moving like she normally does and I felt her move only twice today. Should i be concerned? Should i rather go in tomorrow? Or wqit until Thursday?
