best thing to do is to call your AI technician for pregnancy diagnosis.
some expert can detect as early as 21 days.

take note also that sometimes, in case of silent heaters karaniwan sa mga buffaloes, akala ntin buntis n since no signs of reheat 18-21 days after breeding or even up to 60 days sa iba, based on our experience. hoping n buntis n and at 3 months we palpate di pla.
we often advise sa mga case n ganito to closely monitor their animal especially the heat period since alam ntin every after 18-21 days they will come in heat.
