Fetal heartbeat and fetal bud can be seen in a few weeks.

Under normal circumstances, pregnant women can usually observe the fetal pole via ultrasound examination around 6 weeks of pregnancy. At this time, the fetal pole is approximately 1.2 millimeters long and shaped like a small seahorse. The fetal heart begins to form as well and may display faint signs of a heartbeat. By 7 weeks, the fetal heartbeat becomes more distinct, and a regular heartbeat can be clearly seen and measured. However, these time points are based on averages and may vary due to individual differences. If the mother has irregular menstrual cycles or the exact time of conception is uncertain, development may be slightly delayed. If concerned, it is recommended to consult a physician and undergo ultrasound examination according to the doctor's advice.
