Hey mama! Cord coil is super common actually, a lot of us have encountered that sa BPS ultrasound at hindi naman big deal if the OB didn't flag anything serious, kaya don't worry too much. Pero since it's something noted on your report, best talaga na i-discuss mo in detail with your OB sa next visit para maintindihan mo exactly what it means for your pregnancy and kung may follow-up ultrasound needed. One of my mum friends had it din and her doctor just monitored lang regularly, so usually okay lang siya, pero every pregnancy is different, kaya ang OB mo talaga ang best person to reassure you.
