Hello, the doctor would like to answer your question about whether the fetal heart rate at 7 weeks 120 beats/minute is delayed as follows:
The fetal heart is formed very early, Usually occurs around the 6th or 16th week of pregnancy. By week 7, the fetal heart rate increases and begins to divide into the left and right chambers. You can even see and measure light flashes on the ultrasound machine. Beats per minute start at 90–110 beats/min and increase every day. Fetal heart rate continues to increase until it peaks around week 9, between 140–170 beats per minute for boys and girls.
The fetal heart rate you provided is still within the allowable limits.
If you are still worried, you should go to a reputable medical facility like the hospitals of Vinmec Health System to be examined and consulted by an experienced doctor. Thank you for submitting your question to Vinmec.
