mas sure po if 6-7months na po. nangyari po kasi yan sa brother ko, sabi noon girl daw, tapoa nung nilabas na brother ko, ayun lalaki pala. buti na alng binili ng mother ko nun na mga gamit ay color yellow 😂
usually po around 7 to 8 mos ang safest and most accurate but some can show as early as 16 weeks
