What are the signs before IVF abortion?
IVF is an embryo produced by assisted reproductive technology in the laboratory, and its pregnancy process is relatively complex and fragile. Abortion is one of the common complications in IVF, so many embryos with high potential effect may have spontaneous abortion in the early pregnancy. The following will elaborate on the symptoms before IVF abortion from four aspects.

1. Early pregnancy bleeding
In the early pregnancy of IVF, some women may have early pregnancy bleeding, that is, some vaginal bleeding before the expected menstrual period. This bleeding is usually less than normal menstrual flow, but it lasts for a long time, lasting from several days to several weeks. The symptoms of bleeding may be similar to menstruation, but women should pay attention to whether there are other symptoms, such as abdominal pain, abdominal pain, etc. Early pregnancy bleeding may be a sign of IVF abortion.
In this case, the patient should contact the doctor immediately and receive assessment and treatment in a timely manner. Doctors may recommend blood tests to detect pregnancy problems, and ultrasound tests to determine the health of the embryo.
2. Abdominal pain or abdominal distension
In IVF pregnancy, women may also experience abdominal pain or abdominal distension and pain. These symptoms may be the precursor of IVF abortion. During abortion, the embryo in the uterus will fall off in the uterus, causing severe abdominal pain.
The degree of abdominal pain or abdominal distension and pain may vary from individual to individual. For women with a history of IVF pregnancy, if they have abdominal pain or lower abdominal pain in the early pregnancy, they should immediately consult a doctor for further evaluation and treatment.
3. Pregnant women's body temperature drops
During IVF pregnancy, pregnant women may experience hypothermia. Hypothermia is a common sign of IVF abortion. Under normal circumstances, the temperature of pregnant women will start to rise in the second week of pregnancy and remain at the peak of the temperature curve. If the pregnant woman's temperature starts to drop, it may mean that the embryo has not successfully developed and embedded in the uterus.
Pregnant women can use a thermometer for monitoring to accurately record changes in body temperature. If the temperature starts to drop, the doctor should be contacted in time for further examination and evaluation.
4. Abnormal HCG level
Human chorionic gonadotropin (HCG) is an indicator commonly used for detection and monitoring in IVF pregnancy. Abnormal HCG level may be a sign of IVF abortion. The increase of HCG level is usually a sign of normal development of pregnancy. If the HCG level increases slowly or decreases, it may indicate that there is a problem in fetal development.
Doctors usually advise pregnant women to have multiple HCG tests to track changes in HCG levels. If abnormal HCG level is found, the doctor will further evaluate whether there is pregnancy problem and take appropriate measures. Patients should pay close attention to the doctor's suggestions and cooperate with the treatment plan.
Summary
Signs before IVF abortion may include early pregnancy bleeding, abdominal pain or lower abdominal pain, maternal temperature drop and abnormal HCG levels. These signs may be the manifestation of abnormal embryonic development, and doctors need to be contacted in time for evaluation and treatment. Pregnant women and their families should pay close attention to these signs and cooperate with doctors to increase the chances of success of IVF pregnancy.
