Normal size of gestational sac at 46 days

Pregnancy is a complicated process. After the egg is fertilized, it enters the uterine cavity. The embryo and attachments grow and develop rapidly until they are complete. There are different changes in each week of pregnancy. The gestational sac is the initial shape of pregnancy. The gestational sac is only seen in early pregnancy. For women with standard menstruation of 28 to 30 days, the gestational sac can be seen in the uterine cavity by B-ultrasound after 35 days of amenorrhea. So, how much is the standard value of the gestational sac at 46 days of pregnancy?

The gestational sac at 46 days is about 2.5 centimeters, but there are large individual differences. Because the time of embryo implantation in each pregnant woman is different, the gestational sac will have certain differences, so dynamic detection is required. When there is fetal heartbeat, it means that the gestational sac is developing well. The initial fetal heartbeat can be seen around 8 weeks of pregnancy. For some cases of late implantation, the gestational sac can be considered around 50 days of pregnancy. If no fetal heartbeat is seen after two months, it is necessary to consider that the pregnancy is abnormal, which is mainly caused by abnormal development of the gestational sac.

Generally speaking, a small gestational sac may be due to anxiety, which may cause delayed menstruation, delayed ovulation, and late pregnancy, resulting in a gestational sac that is smaller than the actual number of days of amenorrhea. For example, the menstruation has not stopped for 50 days, but during examination it is found that the gestational sac is only about 40-day size. This kind of small gestational sac is normal. As long as a dynamic examination after one week shows that chorionic gonadotropin and progesterone are gradually increasing, the gestational sac continues to grow, and the embryo, fetal heartbeat and fetal heartbeat gradually appear, it means that the small gestational sac is caused by physiological reasons and you can continue to get pregnant.

The 46th day of pregnancy belongs to the early stage of pregnancy. Some women have already begun to experience early pregnancy reactions and need to make timely and good adjustments. Eating small and frequent meals can alleviate early pregnancy reactions to a certain extent. During the early stages of pregnancy, you must be careful to avoid contact with harmful substances, because it is easy to cause harm to the fetus. This is the peak period of development of the fetal nervous system. If harmed, it is likely to cause deformities.
