bilangan ng months

OB follows the EDD (estimated date of delivery) in the 1st trans v ultrasound of 1st trimester. if walang trans v, use the pregnancy tracker here in this app to estimate your EDD. once alam mo na ang weeks mo. convert it to months. use google. example: type 5 weeks in months. however, mas accurate ang trans v kesa sa LMP (last menstrual period).
