1. What should I do if I have vaginal bleeding in early pregnancy in IVF patients? Many IVF patients have a small amount of vaginal bleeding, and most of them are very nervous. In fact, first of all, the cause of bleeding should be clarified to exclude the possibility of miscarriage or ectopic pregnancy. If incomplete or inevitable miscarriage is found to have occurred, the uterus should be cleared in time to avoid excessive maternal bleeding. If the examination confirms that the pregnancy is ectopic, the patient should be hospitalized for observation and, if necessary, surgical treatment. 2. Is Down’s syndrome screening performed after pregnancy in IVF patients? If there are no other special circumstances after pregnancy in IVF patients, obstetric examination should be performed according to the requirements of normal obstetric examination. Therefore, if the ultrasound shows a single live fetus, Down’s syndrome screening should be done as required. Except for patients with twin pregnancies, or those older than 35 years of age, with a family history of genetic disease or previous births of abnormally defective fetuses. These patients need to go to the genetics department for consultation and can be directly performed prenatal diagnosis. 3.How long do IVF patients generally stop taking the medication until pregnancy? IVF patients have lower hormone levels than normal pregnant patients, so after transplantation, hormone supplementation is routinely performed for fetal preservation, generally until the fetal heartbeat is clearly seen on ultrasound and then gradually reduced to the final discontinuation of the drug at 10 weeks of pregnancy. 4.What kind of delivery method should be used for IVF patients after pregnancy?

One of the more important maternity tests in early pregnancy is the nuchal translucency screening, which can be performed between 10 and 13 weeks of pregnancy to find out whether the fetus is at high risk for Down’s syndrome. 6.What are the precautions in the middle of pregnancy? The most important change during this period is that the mother-to-be will feel the fetal movement, so she should always pay attention to the change of fetal movement and develop the habit of regular exercise, and also change the sleeping position in the middle of pregnancy, try to lie on the left side and strengthen the intake of calcium and iron.
