Can I see the gestational sac on a 35-day ultrasound?

Although many women feel that they may be pregnant, they still need to go to the hospital for examination in the early stages of pregnancy to confirm whether they are really pregnant. The most important thing is to make sure that the embryo is developing in the uterus. Can you see the gestational sac through vaginal ultrasound at 35 days of pregnancy? The development of each gestational sac is different. Some people can identify the presence of a gestational sac in the uterus at 35 days of pregnancy. Let’s learn about the details together.

1. Can vaginal ultrasound show 35 days of pregnancy?

1. The gestational sac is the initial form of pregnancy. It is a small embryo wrapped in the original placental tissue by the amniotic membrane and vascular network. The fetus had not yet formed at that time, but the fetal heartbeat was already there when the embryo bud appeared.

2. The gestational sac is very small at the beginning and then grows slowly. Generally speaking, after 5 weeks of pregnancy, a small gestational sac can be seen on B-ultrasound, which occupies less than 1/4 of the uterine cavity, or a fetal bud can be seen. If it is a normal intrauterine pregnancy, the gestational sac can be seen in the uterus through B-ultrasound around 40 days of pregnancy. However, due to individual differences in the time of conception, some pregnant women may not be able to see it until around 45 days.

3. Usually, when HCG reaches 1000U/L, vaginal ultrasound should be able to identify the intrauterine gestational sac. This is around the 4th or 5th day of the 5th week of pregnancy. When HCG reaches 6500U/L, abdominal ultrasound can identify the intrauterine gestational sac. Therefore, vaginal ultrasound will be more accurate. If the intrauterine gestational sac is not seen on the 49th day of pregnancy during a normal menstrual cycle, ectopic pregnancy should be suspected.

Under normal circumstances, fetal heartbeats can be seen during vaginal or abdominal ultrasound examinations at 5-6 weeks of pregnancy. If the B-ultrasound image clearly shows the embryo but there is no fetal heartbeat, it often indicates fetal death and inevitable miscarriage. However, if the B-ultrasound examination is performed too early, the embryo and fetal heartbeat cannot be seen and it cannot be determined to be abnormal.

Guidance: Hello, if your fetus develops late and the B-ultrasound examination is performed too early, it cannot be determined to be abnormal even if the embryo and fetal heartbeat cannot be seen. I suggest you wait another week to check.

2. Precautions for B-ultrasound examination during pregnancy

1. In the early stages of pregnancy, an ultrasound requires a certain amount of urine to accumulate in the bladder in order to see clearly, so you need to hold your urine in advance. After 3 months of pregnancy, the baby has grown bigger and you don’t have to hold your urine anymore, you can do it whenever you want.

2. Do not do an ultrasound when you are hungry, especially in the middle and late stages of pregnancy. If you are hungry, the baby will not cooperate, and some data may not be clear or can not be measured, or the measured data may be inaccurate.

3. Try to relax as much as possible during the examination and cooperate with the doctor. If you are too nervous during the examination, it may affect the effectiveness of the examination.

4. Do not eat foods that easily produce gas, such as milk, sweet potatoes, etc., before having an ultrasound, because this will hinder the penetration of ultrasound and cause unclear imaging of the examined organs.

5. Before doing the B-ultrasound, caress your belly more and tell your baby to cooperate well, and your baby will cooperate with you.

6. When doing B-ultrasound in the early stages of pregnancy, not every hospital has the conditions to do vaginal ultrasound, so a certain amount of urine needs to be accumulated in the bladder to see clearly. Therefore, if there are special circumstances in the first 3 months of pregnancy and you need to do B-ultrasound, try to drink enough water at home, so that you can save time holding urine when you go to the hospital. However, generally, you don’t need to hold urine for examination after 3 months.
