What is the size of the gestational sac at two months of pregnancy?

Because many women are first-time mothers and lack experience in this area, they will become very nervous once they become pregnant. In fact, this is not good. You should relax. What they want to know most is the development of the fetus, such as the size of the gestational sac two months into the pregnancy. Fortunately, there are many inspection instruments now, and some inspections can be used to determine the size. So let’s take a closer look at how big the gestational sac is two months into pregnancy.

Biparietal diameter: bpd stands for the biparietal diameter of the fetal head, which refers to the data measured by the diameter on both sides of the fetal head and is also one of the indicators for estimating the size of the fetus. According to general rules, it is less than 3 cm at 3 months of pregnancy; after 5 months of pregnancy, it is basically consistent with the month of pregnancy, that is, bpd is about 7 cm at 28 weeks (7 months) of pregnancy, about 8 cm at 32 weeks (8 months), and so on. After 8 months of pregnancy, an average weekly growth of about 0.2 cm is normal.

Placental position: The position refers to the location of the placenta on the uterine wall; the normal thickness of the placenta should be between 2.5 and 5 cm; some report sheets divide the placental position into grades III, grade I is the early stage of placental maturity, with uniform echoes, and this change can be seen at 30 to 32 weeks of pregnancy; grade II indicates that the placenta is close to maturity; grade III indicates that the placenta is mature. The closer to full term, the more mature the placenta is and the more uneven the echo is. If the placenta is detected to be in a too low position, it may block the cervix and affect normal delivery.

Amniotic fluid range: The value of the amniotic fluid range can indirectly determine whether there are any abnormalities in the fetus. Generally speaking, the depth of amniotic fluid is normal between 3 and 7 cm. More than 7 cm indicates increased amniotic fluid, and less than 3 cm indicates decreased amniotic fluid. If there is too much amniotic fluid, it may indicate that there may be abnormalities in the fetus's neural tube or digestive tract; if there is too little amniotic fluid, there may be problems with the fetal urinary system. Fetal movement: Fetal movement can indicate the normal condition of the fetus in the uterus and is an important signal for predicting the safety of the fetus in the uterus. From the 18th to 20th week of pregnancy, most expectant mothers can feel fetal movement, which is mild at first and occurs less frequently. Fetal movements are strongest during the 28th to 32nd week of pregnancy. After the 36th to 38th week of pregnancy, the amplitude and frequency of fetal movements gradually decrease. Fetal movements are more even between 8 and 12 in the morning, least between 2 and 3 in the afternoon, and most frequent between 6 and 10 in the evening.

If the report states "yes" or "strong", it is normal; if it states "no" or "weak", it may be that the fetus is sleeping, or it may be an abnormal situation and needs to be comprehensively analyzed in combination with other items. The fetal position refers to the position of the presenting part in the maternal pelvis, that is, the four phases of the pelvis - left anterior, right anterior, left posterior, and right posterior. The representative bone of vertex presentation is the occipital (abbreviated as o); the representative bone of breech presentation is the sacrum (abbreviated as s); the representative bone of face presentation is the mandible (abbreviated as m); and the representative bone of shoulder presentation is the scapula (abbreviated as sc).

I hope every woman will carefully understand these common sense before getting pregnant. The development of the fetus at different stages of pregnancy is of course different, so it is necessary to have more prenatal check-ups. You may become a little irritable during pregnancy, which is normal. Please stay calm. The hardship will only last for a few months and it will pass if you endure it.
