When a threatened miscarriage occurs, the pregnant woman often experiences abdominal pain and vaginal bleeding. The specific timing of the abdominal pain can vary, as each individual's situation is different. Some may experience longer periods of pain, while others may have shorter ones. During a threatened miscarriage, it is essential to go to the hospital promptly for treatment to preserve the pregnancy. If the bleeding stops after active treatment, then it is possible to continue the pregnancy. However, if the symptoms do not relieve and the pain intensifies after treatment, then it is no longer feasible to continue preserving the pregnancy, and an abortion surgery will be necessary.

What are the symptoms of threatened miscarriage?

Threatened miscarriage refers to a small amount of vaginal bleeding occurring before 28 weeks of pregnancy. Usually, the amount of bleeding does not exceed that of a normal menstrual period, and the blood may be dark red or appear as bloody vaginal discharge. The color of the bleeding is not significant. No pregnancy tissue is expelled initially, and this may be followed by episodic lower abdominal pain or back pain, although these symptoms may not occur. During a gynecological examination, the cervix is closed, the membranes are intact, and the size of the uterus corresponds to the gestational age. After rest and treatment, the symptoms may disappear, and the pregnancy can continue. If the amount of vaginal bleeding increases or lower abdominal pain intensifies, accompanied by the expulsion of pregnancy tissue, it progresses to inevitable miscarriage. Inevitable miscarriage refers to a miscarriage that cannot be avoided. Based on the symptoms of a threatened miscarriage, the amount of vaginal bleeding increases, and episodic lower abdominal pain intensifies, possibly accompanied by vaginal fluid discharge. During a gynecological examination for inevitable miscarriage, the cervix is dilated, and embryonic tissue or the amniotic sac can be seen obstructing the cervical opening.

What is the cause of nausea in threatened miscarriage?

Threatened miscarriage refers to signs of miscarriage during pregnancy, and some women with threatened miscarriage may experience nausea. This situation includes several reasons: First, threatened miscarriage is not the same as a natural miscarriage; women are still pregnant, hence early pregnancy reactions such as nausea are normal. If the nausea is mild, rest and observation are advisable. However, if severe, it is important to visit the hospital for an examination to rule out hyperemesis gravidarum. Second, some cases of threatened miscarriage are caused by gastrointestinal inflammation, such as acute gastritis causing uterine contractions, which then leads to threatened miscarriage. The nausea in these situations is due to acute gastritis, so the nausea is a symptom caused by the condition that leads to the threatened miscarriage, not a direct result of the threatened miscarriage itself.

How long does it take to prevent a threatened miscarriage?

During threatened miscarriage, proactive treatment to preserve the pregnancy is required. However, the duration of such treatment varies from person to person and should be based on the specific circumstances of the patient. If the patient has a history of recurrent miscarriages, in the event of a threatened miscarriage, the pregnancy should be preserved for a longer period, at least until three months into the pregnancy when the fetal development has stabilized. However, if the patient experiences light vaginal bleeding without abdominal pain, and the condition is relatively mild, approximately a week of medication may be sufficient for improvement. It is recommended that one to two weeks after the bleeding stops, a visit to the hospital should be made to perform an abdominal ultrasound to check the embryo's growth.

How long should one stay in bed for a threatened miscarriage?

Threatened miscarriage, as the name implies, is the appearance of signs of miscarriage, such as lower abdominal pain, bleeding, and a feeling of heaviness. For threatened miscarriage, it is appropriate to choose bed rest for treatment, but absolute bed rest is not necessary during threatened miscarriage. Prolonged bed rest is not always beneficial for the recovery of a woman’s health. Being bedridden for a long time can cause constipation, prevent vaginal bleeding from being expelled, and lead to mental stress. It is generally recommended to get out of bed for light activities during the day, aside from normal sleeping hours. Simple, light activities will not worsen the miscarriage. Generally, after a threatened miscarriage, it is advised to rest in bed for 3-5 days at most, and during this period, it is necessary to get out of bed intermittently.

How long should one rest in bed for a threatened miscarriage?

The duration of bed rest for threatened miscarriage varies from person to person. It depends on the patient's clinical symptoms. Generally, one should rest until there is no vaginal bleeding for a week before starting to get out of bed and move around. This is because the typical clinical symptom of threatened miscarriage is minor vaginal bleeding. During this time, in addition to bed rest, it is advisable to take some progestogen medication for miscarriage prevention treatment. After successful miscarriage prevention, most people will see the disappearance of clinical symptoms. Then, one week after the symptoms disappear, they may gradually start getting out of bed but should still avoid intense physical activities.
