How long you have been pregnant, and how long it will take for a fetal bud to appear

Normally, ultrasonography at 42 days gestation can reveal fetal buds and heartbeats. If the average size of the gestational sac is more than 25 mm in diameter and no fetal heartbeat is seen, embryonic termination is generally considered. If your gestational sac is small, considering that the time to conceive is short, there may not be much of a problem, you can continue to observe, and at the same time, in order to accurately understand the development of the embryo, it is recommended to check the blood and HCG for consultation.

Don't worry, check it up later. Fetal heartbeat fetal bud appears at the latest ten weeks, if there is no fetal heart fetal bud at ten weeks. Fetal arrest is considered and termination of pregnancy is required.

Fetal heartbeat and fetal bud are two very important indicators in the first trimester examination, and pregnant mothers are often very excited when they hear the "plopping" fetal heart rate for the first time. Under normal circumstances, fetal buds appear around 6 weeks of pregnancy, and fetal heart tube pulsation can be seen under B ultrasound at 6 to 8 weeks of pregnancy.

However, the appearance time of fetal bud fetal heartbeat is not fixed:

If your menstrual period is inaccurate and often delayed, resulting in an unstable ovulation time, which will affect the estimation of the gestational age, it may take another week to detect the fetal bud and fetal heartbeat.

The gestational age calculated according to the last menstrual period will have a weekly error, and perhaps the fetus in your womb has not grown to the gestational age you think it is, and you need to wait patiently for another week.

In short, pregnant mothers who do not have fetal buds and fetal heartbeat before 8 weeks of pregnancy and do not have any abnormalities can rest in bed and wait for a week before going for a follow-up. The embryonic period changes greatly from day to day, for example, after 50 days of menopause, the fetal heart rate is not seen, and it may come out at 51 days.

Generally about forty days. There are early and late implantations, and if you haven't had it in 52 days now, you can wait for it, and you can go to the ultrasound check in five or six days.

Analysis:

Normally, germ tissue and fetal heart beat can be seen on ultrasound at 7-8 weeks gestation.

According to the results of B-ultrasound, the size of the gestational sac is about 8 weeks of pregnancy, and there is no germ and heart tube pulsation, and the possibility of missed miscarriage is considered, that is, embryo abortion.

Guidance: It is recommended to inject progesterone to protect the fetus**, and recheck the B ultrasound after one week, if there is still no embryo and heart tube pulsation, the missed miscarriage can be diagnosed, and it is meaningless to continue to protect the fetus, and uterine evacuation must be performed.

Because of the development of the embryo, 30-40 days to form the fetal sac, 40-50 days to form the fetal bud, 50-60 days to form the fetal heart, so the general B ultrasound should be done at about 60 days, then you can see whether the fetal sac, fetal bud, fetal heart rate is normal.

The third to four weeks of the first month of pregnancy is called the fetal bud stage. The fetal bud is centimeter-shaped like a small seahorse.
