Two months without fetal heartbeat or embryo

If unhealthy sperm or egg combine together, it will directly affect the health of the fertilized egg. That is why some women do not have a fetal heartbeat or embryo until two months of pregnancy. Normally, in the early stages of pregnancy, the doctor only needs to confirm that it is an intrauterine conception. After about a month, the appearance of the embryonic bud can be seen through instruments. If there is no fetal heartbeat or embryonic bud, the health of the fertilized egg should be considered.

1. Is it normal to have no fetal heartbeat or fetal bud at 58 days of pregnancy?

The main problem is that there is a gestational sac in the uterus but no embryo is seen.

At 7 weeks, B-ultrasound can clearly show the embryo and fetal heartbeat. I don’t know whether your menstruation is normal or the delayed ovulation causes the fertilized egg to implant late, so the fetal age does not match the gestational age. I can’t see the heartbeat for the time being. Wait another week. After all, life is hard to come by. Wait a week and do a B-ultrasound to see if there is indeed no fetal heartbeat, then surgery should be performed as soon as possible to avoid intrauterine fetal death and affect the health of the pregnant woman.

It mainly depends on your menstrual cycle. If the menstrual period is long, it is normal; if the menstruation is normal, it may be an agenetic pregnancy. It is recommended to observe for 10 to 15 days. If an embryo is present, it is normal.

Generally speaking, the gestational sac can be observed around 6 weeks of pregnancy, and the primitive heart tube pulsation and fetal bud can only be observed at 8 weeks of pregnancy. It is not observed now and is considered to be caused by the short pregnancy period. It is recommended that you relax, continue to observe, and have another ultrasound after 10-14 days to understand the development of the embryo.

This is normal. If there is no embryonic heartbeat at 50 days, don't worry as long as there has been no vaginal bleeding or severe abdominal pain before. Seeing the fetal heartbeat at 50 days of pregnancy is just a reference value, because there is a difference between your actual pregnancy time and the pregnancy time used for calculation.

Generally, the heart beat can be seen through B-ultrasound around 8 weeks of pregnancy, and the fetal heart and fetal bud can be seen at 6-7 weeks. If the fetal bud is not seen, it may be due to late fertilization or a certain error in B-ultrasound. Please do not be too nervous. It is recommended that you follow the doctor's advice and go to a regular hospital's gynecology department for a follow-up examination.

2. The size of the embryo

Normally, the embryo can be seen on ultrasound at 6-7 weeks of pregnancy.

4 weeks: The fetus is only 0.2 cm. The amniotic cavity is formed just after the fertilized egg has implanted and its volume is very small. Ultrasound cannot show clear signs of pregnancy.

5 weeks: The fetus grows to 0.4 cm and enters the embryonic period. The amniotic cavity expands and primitive cardiovascular system appears, which may beat. B-ultrasound can show a small gestational sac, which occupies less than 1/4 of the uterine cavity, or a fetal bud can be seen.

6 weeks: The fetus grows to 0.85 cm, and the head, brain alveoli, facial organs, respiratory, digestive, and nervous organs are differentiated. The fetal sac is clearly visible on B-ultrasound, and the fetal bud and fetal heartbeat are seen.

7 weeks: The fetus grows to 1.33 cm. The embryo has the rudiments of a human being. The body segments are fully differentiated, the limbs are separated, and all systems are further developed. B-ultrasound clearly shows the embryo and fetal heartbeat, and the gestational sac occupies about 1/3 of the uterine cavity.

8 weeks: The fetus grows to 1.66 cm. The fetal shape is determined, and the head, body and limbs can be distinguished. The head is larger than the trunk. B-ultrasound shows that the gestational sac occupies about 1/2 of the uterine cavity, the fetal shape and fetal movement are clearly visible, and the yolk sac can be seen.

9 weeks: The fetus grows to 2.15 cm, the head is larger than the body, the various parts are clearer, the skull begins to calcify, and the placenta begins to develop. B-ultrasound shows that the gestational sac almost fills the uterine cavity, the fetal outline is clearer, and the placenta begins to appear.

10 weeks: The fetus grows to 2.83 cm, all fetal organs have been formed, and the rudiments of the placenta are formed. B-ultrasound shows that the gestational sac begins to disappear, a crescent-shaped placenta is visible, and the fetus is active in the amniotic fluid.
