My advise would be to just tell her. Learn to trust your OB, you should be able to tell her anything you want. If hindi ka ganun kakomportable sa kanya, you might want to consider magpalit ng OB. Importante kasi na dapat comfortable ka sa OB mo, kasi dadating ung day na ipapagkatiwala mo sa kamay niya both your life and your baby’s pag manganganak ka na. When that day comes dapat buo ang tiwala mo sa kanya para hindi ka mag-worry.
