No fetal heartbeat or fetal bud at 7 weeks of pregnancy

After pregnancy, pregnant women still have a lot of things to worry about, such as fear of threatened miscarriage, or fear of ectopic pregnancy and other adverse conditions. However, once the embryo grows a fetal heart and fetal bud, the risk of miscarriage is basically smaller. However, many pregnant women have not seen fetal heartbeat or fetal bud at seven weeks of pregnancy. In fact, this is quite normal. Below we will introduce to you some relevant knowledge about fetal heart rate and fetal bud!

1. Fetal heart rate and fetal bud

The fetal heart rate is the heartbeat of the fetus, which can usually be heard in the abdomen with a normal stethoscope between 17 and 20 weeks. The fetal heart rate is 110-160 beats/minute, sometimes even faster and less regular. It becomes more regular towards the end of pregnancy. Sometimes there may be a brief pause in the heartbeat, or the heart rate may reach 180 beats per minute, which is normal. However, if this phenomenon occurs frequently or for a long time, you should seek medical attention in time. The normal fetal heart rate is regular and strong, like the ticking of a clock, at 110-160 beats/minute. If it is <110 beats/minute or >160 beats/minute, you can listen to it again at intervals of 10-20 minutes. If it is still abnormal, it indicates fetal intrauterine hypoxia. If the fetal heart rate is within the abnormal range and is accompanied by irregular fetal heart rhythm, it indicates that the fetal hypoxia is more serious.

The embryonic bud refers to the first two weeks of development of the fertilized egg. Later, various organs gradually form in the embryo before 8 weeks of pregnancy. The period from the third trimester to the first month and four weeks of pregnancy is called the embryonic stage.

2. How long does it take for fetal heartbeat and fetal bud to appear in early pregnancy?

As the embryo develops, the gestational sac is formed in 30-40 days, the fetal bud is formed in 40-50 days, and the fetal heart is formed in 50-60 days. Therefore, B-ultrasound should generally be done around 60 days. At this time, you can see whether the gestational sac, fetal bud, and fetal heart are normal. The period from the third trimester to the first month and four weeks of pregnancy is called the embryonic stage. The embryo is 0.5-1 cm long and shaped like a small seahorse.

3. How to perform fetal heart monitoring?

1. Before doing fetal heart monitoring, you can eat something, which can stimulate the fetus to move more!

2. Before doing fetal heart monitoring, it is best to go to the bathroom, because you may have to stay next to the fetal heart monitor for up to 20 minutes.

3. When doing fetal heart monitoring, it is best to lie on your left side, and you can also put a backrest behind you.

4. Pregnant women will sit on a chair to monitor their fetal heart rate, which is similar to the posture of sitting on a recliner.

5. The fetal heart monitoring operator will tie two small round-shaped devices to the pregnant woman's belly. These two small round cakes, one is used to monitor the baby's heartbeat, and the other is used to record the pregnant woman's uterine contractions.

6. Sometimes, the operator may ask the pregnant woman to press a button when she feels the baby move.

7. The operator can hear the fetal heartbeat and see the fetal heartbeat on an electronic screen. At the same time, the fetal heart rate monitor will also record the uterine contractions on paper.

8. Each fetal heart monitoring usually lasts about 20 minutes.
