40 days old fetus picture

On the 40th day of pregnancy, a pregnant woman can clearly see some of the internal organs, fetal buds, fetal heart rate and heartbeat of the fetus in the gestational sac through B-ultrasound. At this time, the gestational sac is about 2 cm, and the fetus in the gestational sac has grown to about 1 cm, and can basically take on a human shape. This is the early stage of pregnancy, and the fetus is unstable. During this stage, couples should try to avoid having sex, and pregnant women should also pay attention to maintenance and avoid excessive exercise. In most cases, B-ultrasound examination is not recommended. However, if the patient clearly requests it or the pregnant woman has vaginal bleeding, lower abdominal pain or other abnormalities, B-ultrasound can be chosen to check the development of the fetus in the belly.

At 40 days of pregnancy, the size of the gestational sac is about 2.1 cm. An abdominal B-ultrasound examination is usually required for about six weeks of pregnancy before the gestational sac can be found in the uterus. At 40 days, it is recommended to go to the hospital for a female vaginal ultrasound examination. Now it is just a gestational sac, without the yolk sac. In the early stages of pregnancy, you also need to actively take folic acid tablets and take them until three months of pregnancy. This can effectively prevent fetal neural tube defects. In addition, the gestational sac is not very stable during this period of time and it is easy to miscarry, so try not to have sex and don't lower your head.

At 40 days of pregnancy, you can do color ultrasound to see the gestational sac, which is approximately 0.9-3.2 cm in size and occupies approximately one quarter of the uterine cavity. The embryo develops to about 0.4-0.85 cm in size and has the appearance of a test tube embryo. All parts have disintegrated, with the limbs separated and primitive cardiovascular and cerebrovascular diseases present. The embryonic bud, fetal heartbeat and fetal heartbeat fluctuations can be clearly seen under B-ultrasound. During this stage, the fetus's eyes begin to develop, but the eyes are still closed, and the weight of the fetus can be guaranteed to be around 20 grams.

At 40 days of pregnancy, the fetus has no heartbeat. If the normal menstrual period is very cyclical, the fetal heartbeat and embryonic heartbeat can be seen at 45-50 days of pregnancy. If the fetal heartbeat is still not seen after 50 days, it may be that the IVF embryo has stopped developing, which is abnormal. Abortion surgery is required as soon as possible to avoid internal bleeding or uterine infection. Under normal circumstances, if at 40 days of pregnancy, the gestational sac is about 1.5 cm, the fetal bud and fetal heart cannot be seen at this time, but the yolk sac can be seen. Generally, pregnancy at this value is relatively normal. If the gestational sac is relatively small, it may be that the embryo development process is not going well or that the IVF embryo has stopped developing.
