When is the best time to check for fetal heartbeat and胎芽 during pregnancy?

Generally, fetal heart and germ can be detected at 6 to 8 weeks of pregnancy, so it is better to check them at 7 to 8 weeks after the last menstrual period. For women with regular menstrual cycles of 28 to 30 days, the duration of amenorrhea usually matches the gestational week. Typically, the germ can be detected at 6 weeks of pregnancy, possibly without the fetal heart, and the fetal heart can generally be detected at around 7 weeks. For women with longer menstrual cycles, due to later ovulation and implantation of the fertilized egg, the fetal heart and germ may not be visible at 6 to 7 weeks. In such cases, blood tests for human chorionic gonadotropin and progesterone can be conducted for comprehensive assessment. If the values of these two tests are gradually increasing, the embryonic quality is usually good, and an ultrasound examination can be performed after 1 to 2 weeks. After confirming pregnancy, it is important to avoid excessive fatigue, refrain from sexual activity, not lift heavy objects, and avoid vigorous exercise to prevent threatened abortion.
