After an occurrence of embryonic arrest, some early pregnancy reactions in pregnant women will gradually ease but not disappear immediately. This is mainly related to elevated hormone levels in the body. Even after the embryonic arrest, the hormone levels in the body remain relatively high. As the arrested embryo is expelled from the body, the hormone levels will gradually decrease, and some early pregnancy reactions will also gradually ease. Generally, these adverse reactions will gradually ease and eventually disappear about a week after the embryo is expelled from the body.

Does embryonic arrest definitely require a uterine curettage?

After embryo arrest, it is necessary to terminate the pregnancy in a timely manner, but it is not always necessary to undergo a uterine curettage; medication can also be taken orally to help expel the pregnancy sac. Oral medication can stimulate the uterus and soften the cervix to cause uterine contractions and expel the pregnancy sac outside the uterus. However, if the embryo arrest occurs later in the pregnancy, then an artificial abortion is required, which can be done by direct curettage or uterine clearing to help expel the pregnancy tissue. Therefore, it is recommended to go to the hospital for an ultrasound examination after embryo arrest, and then decide whether to choose medical abortion or uterine clearing based on the timing of the examination. (The specific medication should be taken under the guidance of a doctor.)

Embryonic arrest means

Embryonic arrest, as the name implies, refers to the cessation of embryo development. In clinical practice, it is also called fibroid miscarriage. Embryonic arrest is a pathological condition. Normally, in the early stages of pregnancy, as activity increases, the gestational sac gradually begins to show a yolk sac, embryo bud, and fetal heartbeat. If the fetal heartbeat is still not visible after a certain period, it indicates that the gestational sac is in a state of decay and that the embryo has stopped developing. Generally, 9 weeks of pregnancy is considered the final deadline for diagnosis. If no fetal heartbeat is detected during an ultrasound at 9 weeks of pregnancy, it can be diagnosed as embryonic arrest. Once diagnosed, it is advisable to proceed with an abortion as soon as possible to minimize harm to the woman’s body. If embryonic arrest occurs consecutively more than twice, a thorough examination of both partners should be conducted to determine the cause, to guide the next pregnancy.

Will the pregnancy test strip become lighter if the embryo stops developing?

After embryonic arrest, early pregnancy tests will show a fading phenomenon. This is because the embryo has stopped developing, and the level of human chorionic gonadotropin (HCG) in the body no longer rises but instead significantly declines. Early pregnancy tests work by detecting the amount of HCG in the urine. When embryonic arrest causes HCG levels to decrease, the result on pregnancy tests will gradually become fainter, even turning negative. It is advised that in cases of embryonic arrest, prompt miscarriage management or uterine evacuation should be conducted to prevent potential inflammatory gynecological conditions and impacts on the woman's clotting function.

Can embryonic arrest be prevented in advance?

There are no absolute methods in medicine to prevent embryonic arrest in advance, but we can intervene to some extent, such as by conducting pre-pregnancy check-ups. Both spouses should undergo comprehensive examinations at a hospital to see if there are any physical abnormalities that could affect pregnancy. It is also important to avoid exposure to harmful substances during pregnancy, such as working with hazardous materials, exposure to radiation, and consuming contaminated food. Additionally, pregnant individuals should quit smoking, abstain from alcohol, relax, maintain an optimistic attitude, and actively exercise to enhance their immune system.

What is the progesterone level for embryonic arrest?

When an embryo stops developing, the progesterone level will gradually decrease, but how much it can decrease is uncertain; it depends on the gestational age and individual differences. However, if an embryo stops developing, the progesterone level usually does not exceed 20. Therefore, during pregnancy, it is essential for pregnant women to maintain good living habits, avoid harmful factors, rest well, strengthen nutrition, abstain from sexual intercourse in early pregnancy, avoid misuse of medication, and be vigilant about symptoms like vaginal bleeding or abdominal pain.
