Placental Calcification

Hi. Anyone here diagnosed with placental calcification? Nag pa utz ako yesterday and doctor noted this in my result. Apparently the calcifications are too early for my AOG at 33 weeks. It usually comes week 37 onwards. My OB naman told me that with calcifications in the placenta, I may go into labor early. Need to monitor daw. Sana kaya pa din mag normal delivery.
