accurate po ba tong app na to kung ilang weeks na po akong preggy?

nothing is accurate, kaya estimated ang tawag. hindi masasabi kung kelan nangyari ang fertilization/conception. 2 types ang basis ng AOG, LMP or ultrasound. if regular ang cycle, pwedeng magbased sa LMP. if not regular, as per OB, use AOG/EDD from 1st TVS.
