What is a gestational sac?
Gestational sac is the original placental tissue, a small embryo wrapped by amniotic membrane and vascular network, which can only be seen in the first trimester. For women with menstrual cramps for 28-30 days, after 35 days of menopause, the gestational sac can be seen in the uterine cavity by B-ultrasound, and the fetus has not yet formed.
Gestational sac to see men and women
It is said that the sex of the fetus can be judged by looking at the shape of the gestational sac on the B-ultrasound list.
If the gestational sac is more than doubled in length and width and has a long shape, then it is very likely to have a male baby.
If the gestational sac is equal in length and width, or oval or round, it is probably a female baby.
Is gestational sac accurate for men and women?
Some people use the size and shape of the gestational sac to judge the sex of the fetus. So is the gestational sac accurate for men and women?
Rumor: the gestational sac is long, so it is more likely to be pregnant with a male baby; If the gestational sac is oval or round, it is likely to be a female baby.
Explanation:
The size and shape of pregnancy sac of expectant mothers have nothing to do with the sex of the fetus, but are determined by many factors such as pregnancy time, nutrition, implantation position and uterine cavity size.
1. Generally, a well-developed gestational sac is round and flat, but sometimes it will become longer with the shape of the uterine cavity. The shape of the gestational sac is actually determined by its tension and amniotic fluid content, and will change its shape by itself. So the date of pregnancy is different, and the gestational sac you see may be different.
2. The shape of gestational sac also depends on the condition of pregnant women at the time of examination. For example, some pregnant women flatten their uterus and the shape of the gestational sac looks flat because of the long urination time.
3. When some pregnant women are pregnant, the implantation position of sperm and eggs is just right, and some positions will be deviated, resulting in different shapes of gestational sacs.
4. The direction of the B-ultrasound probe is different every time, and the shape of the gestational sac at different angles is also different.
To sum up, we can know that the shape of the gestational sac can not judge the sex of the fetus. But pregnant women should pay attention to the shape of the gestational sac to judge whether the fetus is healthy or not.
The shape of normal gestational sac
The gestational sac is about 2 cm in diameter at the sixth week of pregnancy and 5 cm in diameter at the 10 week of pregnancy. The position of gestational sac is normal in the bottom, front wall, back wall, upper part and middle part of uterus.
If the gestational sac is round, oval and clear, it is normal. For example, the gestational sac is irregular and fuzzy, and the position is below. If pregnant women have abdominal pain or vaginal bleeding at the same time, they may miscarry.
Pregnant boys and girls have long known
During pregnancy, the pregnant woman's body will have different degrees of pregnancy reaction, and the symptoms of pregnancy are also different. There is a very popular feature that has been known for a long time, such as the strength of morning sickness, the speed of fetal heart, the color of areola and the roundness of the stomach. Are these characteristics of pregnant boys and girls really accurate? The following is an interpretation of the folk saying that boys and girls are born, to see if pregnant mothers have these characteristics, and whether these characteristics can really know that boys and girls are born.
Symptoms give birth to boys and girls. I explain morning sickness. There was no severe morning sickness in the first trimester. You will encounter severe morning sickness in the first trimester. There is not enough scientific evidence. Morning sickness is caused by the rapid increase of human chorionic gonadotropin (HCG) in early pregnancy, which inhibits gastric acid secretion, thus affecting the appetite and digestive function of expectant mothers. Whether it is a boy or a girl, morning sickness can happen. The personal experience of many pregnant women also shows that the severity of morning sickness has nothing to do with the sex of the fetus. Fetal heart rate Fetal heart rate is less than 140 beats/min. Fetal heart rate should be at least 140 beats/min. This statement is not credible. The fetal heart rate of a female baby is higher than that of a male baby, only at birth. When they are both fetuses, there is no difference in the heart rate between male and female fetuses. Areola areola is relatively dark in color. Breast enlargement is obvious; The left chest is bigger than the right chest. Nipple Black Boy is not reliable. After pregnancy, progesterone in the expectant mother's body will stimulate the increase of melanocytes, leading to the darkening of some parts of the body. Therefore, pregnant women with girls, areola will also turn black; In addition, due to the secretion of progesterone, regardless of the sex of the fetus, the breasts of pregnant women will increase to varying degrees. A bulging belly looks like a full and round basketball. A bulging belly looks like a big watermelon, but it doesn't look as round as a ball. It is common to see the sex of the fetus through the shape of the belly, but it is not accurate. In fact, the shape of the belly during pregnancy has nothing to do with the sex of the fetus, but with the body shape of the pregnant mother. Because everyone's body shape is different, the shape of pelvis will be different. Relatively speaking, when a fat person is pregnant, his stomach will look more round. On the contrary, if she is thinner, her stomach will become sharper.
