Aww mama, yan talaga ang confusing part, ang dating ultrasound versus ang BPS dating, kaya ikaw lang dapat magtanong directly sa OB mo which one she's following para sa management mo, kasi iba-iba ang approach ng bawat doctor at that matters talaga sa labor planning! A few of us mums had the same situation and nag-follow lang kami ng preferred date ng OB namin, then we trusted their judgment since they know our case best, ang peace of mind na hindi ka na nag-alala kung anong date to follow ay sobrang worth it, promise.
