How many days of pregnancy can I do ultrasound, and how long does it take to get pregnant

The gestational sac can only be seen after 5 weeks of gestation, and the detection rate of gestational sac at 6 weeks of pregnancy is 100%.The embryo can be seen at 6-7 weeks of gestation, and at 49 days of gestation, the original heart tube pulse can be seen when the germ diameter is 2mm, and it begins to take on a human shape at 8 weeks of pregnancy. All organ formation ends at week 14.

At the end of the 15th week, the hair begins to appear, and by the end of the 16th week, the uterus is about 16cmAt the end of the 17th week, the baby's movement is restricted and fetal movements occur. The second scan was completed at week 21 (gender was discerned).

The gender is known at the end of week 22.

Ideally, it is easy to see at 8-10 weeks of pregnancy. Moreover, it is not easy to see the shadow of the gestational sac if you do B ultrasound too early, and it will theoretically be ** to the fragile, just formed embryo, which is not conducive to embryonic development, and it is best to avoid doing B ultrasound too early, or doing B ultrasound many times.

Check up once within 12 weeks (3 months) of pregnancy to recognize the symptoms of early pregnancy in time and start health care as early as possible. In the second trimester of pregnancy (13-28 weeks of pregnancy), check once a month to screen for high-risk pregnancies in a timely manner, increase the number of examinations as appropriate if high-risk factors are found, and give necessary corrections**. In the third trimester of pregnancy (28-36 weeks of pregnancy), it is checked every six months to detect various factors that affect normal delivery, complications and complications during pregnancy.

Hello, according to the situation you described, 7 weeks after pregnancy, you can see whether it is in utero, and you can see whether there is a fetal heartbeat and fetal buds. At the end of the third month of pregnancy, the organs of the fetus have matured, and most of them can distinguish between men and women. Pay attention to rest, increase nutrition, maintain a happy mood, and take folic acid tablets orally to 3 months of pregnancy, do you have any other questions?

It is best to go at three months, at this time the fetal baby is still very clear in all aspects, if there is no special situation, the number of prenatal examinations done B ultrasound The doctor will tell you.

After more than 35 days of menopause, the early pregnancy test strip test is positive, and the gestational sac can generally be seen by endocavital ultrasound. A gestational sac can be seen on transabdominal ultrasound for more than 45 days. There is no abdominal pain or bleeding during this time period, and the color ultrasound is rechecked a week later, and the embryo and fetal heart rate can be assured, and the follow-up regular prenatal examination will be carried out.

If the embryo is not visible after one week, blood HCG should be combined, closely observed, fetal preservation or sterilization should be considered.

For first-time pregnant women or pregnant mothers with normal pregnancies, ultrasound examination is generally recommended more than 50 days after menstruation. The purpose of this ultrasound examination is to observe the development of fetal heartbeat and fetal buds. If the fetal heartbeat and fetal bud development are normal, it means that the embryo is developing normally, and you can wait until three months later for routine prenatal examination.

For pregnant women with regular menstruation, the gestational sac can be seen at the earliest 35 days, and the development of fetal heart rate and fetal buds will occur around 46 days after menopause. So, it is recommended that it can be in more than 50 days. Do a B-ultrasound examination.

For pregnant women with irregular menstruation, when doing B ultrasound for more than 50 days, it is possible that the fetal heart rate and fetal bud cannot be seen. Therefore, at this time, you can expect 7-10 days to re-examine the B-ultrasound. Only when the fetal heartbeat and fetal buds are observed to appear, it means that the baby is developing normally.

In this case, you can wait until three months later to retest. Therefore, for most pregnant women, it is generally recommended to have a B-ultrasound examination about 50 days after menstruation.

If you want to know exactly if you are pregnant, you can go to the hospital to check the blood and see the level of the chorionic hormone, so that you can know! My answer!

As the saying goes, Rome wasn't built in a day, and children weren't necessarily born. The child also grows up day by day in the mother's womb, and what a great thing it is for a mother's love to give birth to a new life. A mother's love for her children begins in the womb.

So there is such a thing as B-ultrasound. How long does it take to get pregnant to have a B-ultrasound?

Under normal circumstances, in the first trimester of pregnancy (about 12 weeks of pregnancy), pregnant mothers should have a B-ultrasound examination. Pregnant mothers should avoid doing ultrasound too early, or doing ultrasound multiple times. Doing ultrasound too early may lead to fragile, newly formed embryos, which is not conducive to embryonic development.

In the first trimester of pregnancy, ultrasound is done to determine whether there is pregnancy and the number of days of gestation, to provide a reliable basis for determining the expected date of delivery, and to detect whether the embryo development is abnormal in time.

The second ultrasound examination is generally arranged in the second trimester of pregnancy (about 20 weeks of pregnancy), when the intrauterine amniotic fluid is relatively large, the fetal size is relatively moderate, and there is a large space for movement in the uterus. More obvious malformations, such as congenital heart disease, anencephaly, hydrocephalus, spina bifida, abdominal wall defects, short limbs, polycystic kidneys, gastrointestinal atresia, etc., are easy to find. If necessary, the pregnancy can be carried out in a timely manner** or terminated.

The third ultrasound examination should be scheduled in the third trimester of pregnancy (about 28 weeks of pregnancy) to understand the development of the fetus in utero and to recheck the fetus for malformations. Because there are some diseases in the second trimester, ultrasound may not be able to detect them in time.

If the pregnant mother has not delivered two weeks after the due date, the doctor may recommend another ultrasound to understand the placenta, amniotic fluid, fetal position, etc., and help the doctor decide which delivery method is safe.

If the pregnant mother suffers from certain diseases, ultrasound examination is more important. The number and time of ultrasound examinations during pregnancy should be arranged by the doctor according to the pregnancy situation.

1. The first examination time is at 18-20 weeks of pregnancy, at this time, it can determine whether it is a single fetus or multiple fetus, and the fetal head circumference can be measured. Because the error of fetal ultrasound indicators at this stage is small, it is convenient to check the gestational age.

2. The second examination time is scheduled at 28-30 weeks of pregnancy. At this time, the purpose of ultrasound is to understand the development of the fetus, whether there are body surface malformations, and to further understand the position of the fetus and the amount of amniotic fluid.

3. The last time is at 37-40 weeks of pregnancy, and the purpose of B ultrasound examination at this time is to determine the fetal position, fetal size, placental maturity, whether there is umbilical cord around the neck, etc., and conduct the final assessment before labor.

If there are other special circumstances, you need to do B-ultrasound in the first trimester, and you should go again after 6 weeks of pregnancy, so that B-ultrasound can be visualized at this time, and you can't go to B-ultrasound too early.

Summary. 6-7 weeks.

The first ultrasound examination during pregnancy is carried out at 6-7 weeks of pregnancy, that is, about 40-50 days after menopause, it is not recommended to carry out ultrasound examination too early, so as not to make the fetal sac too small to be found, at this time, the B ultrasound examination can be carried out to clarify whether the fetal sac is consistent with the number of days of menopause, to avoid fetal abortion, and to clarify whether the fetal sac is in the uterine cavity, excluding the possibility of ectopic pregnancy.

How long does it take to get pregnant to do a B-ultrasound.

The first ultrasound examination during 6-7 weeks of pregnancy is carried out at 6-7 weeks of pregnancy, that is, about 40-50 days after menopause, it is not recommended to perform B ultrasound examination too early, so as not to make the fetal sac too small to be found.

Theoretically, it is possible to tell the sex of the fetus, but now the hospital generally does not tell you, and sometimes it may hint at you.

Hope mine is helpful to you.
