The : The level of HCG above which you should see a gestational sac in the uterus is usually between 1000 and 2000 depending on the blood test being used, the quality of the ultrasound machine, the experience of the radiologist. Most would not state that 900 is a high enough level to definitively say you should see a gestational sac in the uterus. In the absence of symptoms of pain, most would choose to follow the HCG level over time. If it is not rising by 25% in 24 hours or 50% in 48 hours then it is an abnormal pregnancy. Once the level gets to the "critical level", if the pregnancy is not seen in or out of the uterus, a definitive statement about the probability that the pregnancy is ectopic can be made. The key is very close contact with the doctor following you to make sure that intervention comes as soon as the facts support it. An ectopic pregnancy is a very serious thing and needs to be diagnosed as soon as possible.
