huling regla kupo ay January 19 kailan kya pusibleng nabuo si bby ? January po b o February#pleasehe

Ay sis, based sa January 19 last period mo, most likely ay nangyari around early February ang conception, usually around 2 weeks after ang start ng period mo, kaya roughly late January to early February! Para mas sure ka though, mas okay kung tanungin mo ang OB mo sa next check-up para exact dating nila based sa ultrasound, kasi that's the most accurate way para malaman mo talaga.
