How long can an embryo stay in the womb?

If the fetus stops growing during pregnancy, termination of pregnancy is generally required. Fetal arrest actually refers to the cessation of embryo development, which is a stage in miscarriage. It occurs when an ultrasound examination finds that the fetal sac is underdeveloped, or there are no signs of growth after one to two weeks of observation, or there is a process from having a fetal heartbeat to having no fetal heartbeat.

How long can the embryo stop developing in the womb?

The condition of fetal cessation of development is very serious. The time the fetus stays in the uterus after development cessation is difficult to judge. This needs to be decided in combination with the specific situation of the pregnant woman. If the retention time is too long, it is considered a missed abortion. Therefore, during pregnancy, regular prenatal examinations must be carried out to understand the actual development status of the fetus. If fetal development cessation occurs, corresponding solutions must be taken in time.

Symptoms of fetal growth retardation

Fetal growth retardation refers to the cessation of growth and development of a test tube embryo, that is, the cessation of growth and development without the birth of a fetus. It is different from miscarriage in the middle and late stages of pregnancy. If the embryo stops developing, all pregnancy reactions of the pregnant mother will gradually disappear.

1. There are no more early pregnancy reactions such as nausea, vomiting, etc., and the feeling of breast swelling will also weaken.

2. There is also bleeding in the vagina, often with dark red bloody leucorrhea.

3. You may also experience lower abdominal distension and pain, and the test tube embryo may be expelled.

The above symptoms vary from person to person. Some people may not even have any symptoms, but may experience abdominal pain immediately, followed by miscarriage, or the embryo may stop developing and then be discovered through basic B-ultrasound examination without any symptoms.

Therefore, when you are 6-8 weeks pregnant, once you feel that the pregnancy reaction is gradually alleviated, such as no more nausea, vomiting and other early pregnancy reactions have subsided, and the feeling of breast swelling has weakened, you should be alert at this time. This situation can be regarded as an early symptom of fetal growth retardation. Some patients have vaginal bleeding with dark red bloody leucorrhea, and some patients have lower abdominal distension and pain. You need to go to the hospital for examination immediately.
