If a woman's menstrual cycle is delayed for a long time and she engages in sexual activity during this period, she can consider whether she is pregnant. There are many methods to detect pregnancy, such as early pregnancy test paper, HCG test, ultrasound, etc., all of which are good early pregnancy detection methods. So what does pregnancy yellow sac mean?
When women engage in sexual activity without contraception, sperm and egg combine to form a fertilized egg, which implants in the uterus and develops into an embryo. At this time, women should promptly go to the hospital for examination to see if the fetus is healthy. However, the first structure discovered during ultrasound testing is the gestational sac, which is also known as the yolk sac.
As the gestational sac continues to develop, the yolk sac will produce fetal buds and fetal heart, and gradually the fetal heart pulsation can be seen. So the yolk sac is the initial form of the fetus, and pregnant women need to pay attention to changes in the yolk sac at all times. Because only when the yolk sac develops healthily, the fetus will be healthier.
The first ultrasound examination after pregnancy is recommended to be conducted between 5-7 weeks of pregnancy, as the fetal bud and heart have already developed and formed. If the ultrasound detects fetal bud and heart pulsation, it indicates that the fetus is healthy. If the ultrasound does not detect fetal bud and heart pulsation, it suggests that there may be abnormalities in the embryo. Women should pay attention to rest and eat more fruits and vegetables after pregnancy, which is more conducive to the healthy development of the fetus.
