When is the latest time for twins to have fetal heartbeat and fetal bud?

I believe everyone hopes to have twins, but this is a low-probability event, so it cannot be forced. In the early stages of pregnancy, when pregnant women go to the hospital for a check-up, an important task is to check the fetal heartbeat and fetal buds. As long as everything is normal, there will be fetal heartbeat and fetal buds at 60 days of pregnancy. However, if you are pregnant with twins, the development speed may be slightly different. So how long will it take to see the fetal heartbeat and fetal buds of twins?

The latest fetal heart rate and fetal bud of twins:

Under normal circumstances, the embryo and fetal heart rate will develop in the gestational sac more than 50 days after pregnancy, which is about 50 days after menstruation stops. It is recommended that if the menstruation is about 70 days and there is no embryo or fetal heartbeat development, and if there are no other symptoms, you can observe for a few days and then do another examination. If it is confirmed that there is no embryo or fetal heartbeat, it is said that the baby is intrauterine arrest and the only option is abortion.

If the menstrual cycle is regular, the embryo and fetal heart rate can be checked in the seventh week of pregnancy. Now it is a twin pregnancy. If the conception and implantation time is late, you can check again after one week. If there is still no obvious fetal heart rate, it is fetal growth retardation and there is no way to continue the pregnancy. There are many reasons for fetal growth retardation, such as low progesterone, abnormal fetal development, chromosomal abnormalities, intrauterine viral infection, exposure to radiation or toxic chemical raw materials, etc.

Weak primitive heart beats can usually be seen at 5 weeks of pregnancy. Fetal heart beats appear at 6 weeks.

Some of them appear later, around 50-60 days later. If they do not appear after 60 days, they will basically not appear again!

Generally, in a twin pregnancy, the two gestational sacs may be identical twins or dizygotic twins. In a twin pregnancy, normal fetal heartbeat and fetal buds can be seen at around 56 days of pregnancy at the latest.

Generally, an obvious embryonic bud will appear around the 45th day of pregnancy, so it is likely to be a withered egg. It is best to perform a timely uterine cleaning, otherwise it is easy to cause heavy bleeding or infection. It is recommended to actively handle the abortion. No sexual intercourse or pelvic bathing within one month after the abortion, no heavy physical work for half a month, eat more nutritious and easily digestible food, eat more fresh fruits and vegetables, strengthen your physical fitness and improve your immunity.

Generally speaking, the embryonic bud can be seen at the sixth week of pregnancy, and the fetal heartbeat can be detected under B-ultrasound at the eighth week of pregnancy. My wife is now ten weeks pregnant and there is still no fetal heartbeat or embryonic bud, so the possibility of fetal arrest is very high. My wife is saying that she is having twins, so it is possible that the fetuses are smaller. But even if they are smaller, the difference will not be more than two weeks. Therefore, since there is no fetal heartbeat, you should have an abortion as soon as possible. Otherwise, the dead fetus will be a foreign body stimulation in the uterus, which is not conducive to the recovery of the uterus.
