6weeks and 3 days

Pray lang po, a fetal heartbeat may first be detected by a vaginal ultrasound as early as 5 1/2 to 6 weeks after gestation. That's when a fetal pole, the first visible sign of a developing embryo, can sometimes be seen. But between 6 1/2 to 7 weeks after gestation, a heartbeat can be better assessed kaya pinapabalik kayo next week baka meron na, kasi meron po yang rule na "heartbeat by seven weeks" :)
