Usually, staph is clearly diagnosed at 8-10 weeks of pregnancy. When no gestational sac is seen in the uterus and the HCG level is abnormally high, the possibility of staph should be suspected. Staph is an abnormal pregnancy that can be life-threatening if not treated promptly. Staph is a benign trophoblastic tumor, so it is also called benign staph. At the beginning of pregnancy, the pregnant woman does not feel anything, she has normal vomiting reaction, nausea, and the blood HCG level is normal. However, when there is no gestational sac or fetal heartbeat in the uterine cavity at the ultrasound examination around 8 weeks of pregnancy, instead there is a falling snow or honeycomb image in the uterine cavity, it is considered as a gravid fetus. If it is a gravid fetus, it is necessary to give timely clearance surgery, which usually requires two clearings with an interval of one week, and the blood HCG level should be rechecked regularly after the surgery until it returns to normal. There are many factors that can cause staph, such as nutrition, infection or some genetic immune mechanism problems. It is possible for women in their reproductive years to have staph and is common in pregnant women between 20 and 30 years old. After the occurrence of staph, it is important to terminate the pregnancy as soon as possible. Therefore, it is important to complete all tests after pregnancy. Usually at 8 weeks of pregnancy, if the fetal heartbeat and fetal pressure are visible in the uterus, the possibility of staph can be ruled out.
