The gestational sac is the embryonic tissue gradually formed by the implantation and development of the fertilized egg. The appearance of the gestational sac indicates that the pregnancy is continuing to develop well. Therefore, some expectant mothers may think that by observing the condition of the gestational sac, they can understand whether the embryo is growing and developing healthily. Recently, some expectant mothers want to know what is the normal size of the gestational sac at 15 days of pregnancy?
In the initial stage of pregnancy, it is not easy to see the gestational sac, mainly because it is still too small to be observed even under ultrasound. As the gestational age continues to increase, the gestational sac will gradually grow. Generally, it can be seen under ultrasound after about 6 weeks of amenorrhea in women. At this time, the gestational sac accounts for less than 1/4 of the uterine cavity and is well-developed, and fetal buds may also be seen, which is also the time to rule out ectopic pregnancy.
Because the size of the gestational sac can affect the development of the embryo, but as long as the embryo development is normal during the prenatal examination, women do not need to worry. During pregnancy, it is important to pay attention to strengthening nutrition, maintaining a balanced and reasonable diet, especially eating more protein, which can promote the development of the gestational sac. At the same time, women also need to supplement folic acid in the first three months of pregnancy, which can not only promote the development of the gestational sac but also prevent fetal neural tube defects.
But sometimes when a woman undergoes a pregnancy check-up and finds that the gestational sac is smaller than the actual number of days of amenorrhea, she should not be nervous for the time being, because the small gestational sac may be caused by delayed menstruation, delayed ovulation, or delayed conception due to certain reasons. As long as the HCG hormone and progesterone levels increase normally after a week of dynamic examination, the gestational sac continues to grow, and there are fetal buds and fetal hearts, it indicates that embryonic development is normal.
