It took 85 days of pregnancy for the fetal heartbeat to appear.

The issue that mothers are most worried about after pregnancy is whether the baby's physical development is healthy and whether it meets the normal fetal development standards. Therefore, once pregnant women become pregnant, they begin to run around hospitals of all sizes and do various checkups regularly. In addition, they will also do some extra checks to ensure the baby's health. The fetal heartbeat and fetal bud will appear first, so how long does it take for the fetal heartbeat and fetal bud to appear? In addition, let us understand what fetal heart rate and fetal bud are.

The development of the fetus is an issue that many pregnant women are concerned about. As a first-time mother, they will always pay attention to the growth of the fetus, from the embryonic bud and fetal heart rate at the beginning to the size in the later stages of pregnancy. In the early stages of pregnancy, the fetus initially goes through a bud stage, and usually fetal pressure and heart rate appear around two months into the pregnancy.

1. Fetal heart rate and fetal bud

What we usually call the embryonic bud refers to the initial form of the fertilized egg when it develops in the mother's body, that is, the pregnant egg formed during the initial embryonic development. Everyone knows that the gestational age during pregnancy is generally calculated based on the time of the last menstrual period, so the time when the fetal heartbeat and fetal bud appear is also different. The normal development of the embryo requires the formation of a gestational sac first, then a fetal bud, and then a fetal heartbeat. Examination at this time is helpful for prenatal examinations to confirm whether the development is normal.

2. Time when the embryo bud and fetal heart appear

Because everyone's physical condition is different, the time when the embryo bud and fetal heart rate appear is not fixed, but an approximate time. Generally speaking, it may be reflected in color ultrasound at the latest two months, and can also be calculated according to gestational age. However, it is different for some people. The embryo may appear at the fifth week of pregnancy, but the fetal heartbeat will not be seen until the eighth week of pregnancy. If there is no fetal heartbeat after eight weeks of pregnancy, there may be a problem of embryonic arrest, that is, the fetus has stopped developing abnormally.

Since each stage of fetal development has a corresponding cycle, any developmental abnormalities will cause it to remain at a certain stage. Some people are very anxious if they haven't seen the fetal heartbeat after 40 or 50 days. In this case, you need to confirm your menstrual cycle and ovulation period, because different factors will cause the fetal heartbeat to appear at different times.

During the prenatal check-up, the appearance of the embryo and fetal heart rate can be confirmed through B-ultrasound examination. If there is abnormal bleeding, there may be problems with the quality development of the embryo. The timing of the gestational sac can also be inferred through progesterone or hormone testing.
