mga mi kailan po kaya nabuo si baby or kailan po ako nakipag do at nagresult ng pagbubuntis ko?

Based sa last mens mo ng March 20-24, likely nag-ovulate ka around early April, so yung conception ay around that time din, meaning ngayon baby mo is around 8-9 months na sa tiyan mo if we're in late November/early December na! The baby's development started right after conception, but ang heart beat at basic features ay naka-form na by 8-12 weeks pa lang, so sobrang ganda na ng progress ng little one mo by now. Best to confirm exact dates with your OB though kasi sometimes LMP alone might be off by a week or two, especially if walang regular cycle ka!
