At 42 days pregnant, you can see the fetal bud and fetal heartbeat.

Under normal circumstances, pregnant women can see the embryo at 42 days of pregnancy, but they cannot hear the fetal heart for the time being. Pregnant women must maintain a stable state of mind and eat a healthy and reasonable diet. Usually, they will pass B-ultrasound after two months of pregnancy, and can clearly see the fetal heart and embryo.
