How long can I see fetal buds and fetal hearts?

When I am pregnant, I will encounter various worries and uneasy to go to the hospital for examination.

Go early, B -ultrasound will not see the fetal buds and fetal hearts.

Early, check the level of blood HCG and progesterone "low" and worry.

Going late, I will not be assured.

In fact, there is really no need to go to the hospital for examination after delaying menstruation. Otherwise, you will cause trouble. In addition to repeated blood drawing B -ultrasound, you will also have to take medicine and injection. ""Being tire" is completely unnecessary.

In terms of judging whether the embryo survives and whether it is necessary to protect the fetus, the level of blood HCG and progesterone is not reliable at all, but it is easy to mislead people.

The most reliable indicator is to see germ and fetal heart beating under B-ultrasound. For women with normal menstruation (once every 28-30 days, once every 28-30 days), after 6 weeks of menstruation, B-ultrasound can see germ and heart beat beats.Essence

Before that, there is no need to frequently check HCG and progesterone levels to do B -ultrasound.

If you do this, it is too much too so.

However, if obvious abdominal pain and vaginal bleeding occur during the waiting period, you still have to see the emergency treatment and B-ultrasound, because the probability of abortion of early pregnancy is 10-15%, and the probability of ectopic pregnancy is 1-2%.

How long is the pregnancy and how long menopause is two different things

The various situations we usually call are calculated according to the regular menstruation, that is, the default menstruation is very regular. The menstrual cycle is 28-30 days, and the 14th ovulation is ovulation on the 14th of menstruation.

In this case, the time to discontinue menstruation and pregnancy is consistent. If it is irregular menstruation, or the menstrual cycle is relatively short/long, the discontinuation and pregnancy time will be inconsistent.

Ovulation with a short menstrual cycle will be relatively early, and pregnancy time will be greater than menopause time.

If the menstrual cycle is relatively long, the ovulation time is usually relatively late, and the pregnancy time will be less than menopause.

"Three Animals": Basis, Evidence, Data

Recently, I have been emphasizing that things and things need to be "three based", that is, basis, evidence and data.

The following is the "three evidences" of my article.

A summary article was published in the "New England Medical Journal" to explain the standards of the American Society (SRU) in detail.

Only when the ultrasonic examination meets any of the following standards can the diagnosis of embryos stopping can be diagnosed, and no need to continue to wait:

1.Head and hip length (CRL) ≥7 mm, no heartbeat;

2.The average diameter of the gestational sac is ≥25 mm, and there is no embryo;

3.Ultrasonic inspections found that there is no yolk sac for gestational sacs. After the review of ≥ 2 weeks, no embryos with heart beating are still found;

4.Ultrasonic examinations found that there is a yolk sac for a yolk sac. After ≥ 11 days, no embryos with heart beat were found.

The following is the situation where ultrasound examination is suspected of abortion, but the diagnosis cannot be clearly diagnosed. It can be expected:

1.The length of the head and hip <7 mm, no heartbeat;

2.The average diameter of the gestational sac is 16-24 mm, without embryo;

3.The ultrasound examination found that there was no yolk sac for a gestational sac. No heart-fighting embryos were found after 7-13 days;

4.Ultrasonic examination found that there is a yolk sac for a yolk sac. After 7-10 days, no embryos with heart beating were found;

5.No embryos were found at least 6 weeks after menstruation;

6.Empty shencum (amniotic sac is adjacent to the yolk sac and no embryos are found);

7.Eap (> 7 mm);

8.Compared with embryo, the pregnancy sac is relatively small (the difference between the average gestational sac diameter and the length of the head and hip is less than 5mm).

Summarize

Useful knowledge has increased:

1. For women with normal menstruation, after 6 weeks of menstruation, you can see germ and heartbeat.Before that, there is no need to frequently check HCG and progesterone levels to do B -ultrasound.

2. Say things that do things with "three evidence": basis, evidence and data.
